OriginGPS enhances customer
support globally with new
Future Electronics partnership
OriginGPS, a manufacturer of miniature
Global Navigation Satellite System (GNSS)
modules, has made a worldwide distribution
agreement with Future Electronics.
OriginGPS’ low-power GNSS modules will
be marketed through the specialist wireless
and RF business unit, Future Connectivity
Solutions.
OriginGPS’ latest modules include the
Multi Micro Hornet, the world’s smallest
multi-GNSS module, and the Nano Spider, a
miniature GPS receiver with an integrated
receiver that measures just 4.1mm x 4.1mm
x 2.1mm. They are able to pinpoint locations
accurately to within around 1m with a
tracking sensitivity of -163dBm.
World’s first 1nF temperature
compensation-type monolithic
ceramic capacitors in 0201
case
Murata has announced the introduction of
an 0201 size (0.6mm × 0.3mm), 25V
temperature compensation-type monolithic
ceramic capacitor with CH/C0G
characteristics. These capacitors are the
world’s first in this size to achieve a
capacitance rating of 1nF.
The largest capacitance available
previously in 0201 size 25V capacitors was
220pF. The new GRM0332C1E102JA01
and GRM0335C1E102JA01 show little
variation in capacitance due to temperature
fluctuations or DC bias.

Industry 4.0: a great tagline – but what
does it mean for those at the front line
of industrial system design?
From the World Economic Forum in Davos, Switzerland, to the Embedded World
exhibition and conference in Nuremberg, Germany, there is one big theme
occupying the minds of industry leaders, business people and engineers at this
moment: the so-called Industry 4.0, or the Fourth Industrial Revolution.
Of course, the term ‘Industry 4.0’ provides a great tagline for conferences. But
what does it mean in practice for the electronics engineers who have responsibility
for realising the grand vision?
One of the key elements of the fourth industrial
revolution is the idea of the ‘smart factory’, in
which almost every aspect of the building’s
operation benefits from intelligent automation.
Of course, industrial automation itself is far from
a new concept: even as long ago as the early
years of the 20th century, Henry Ford was
inventing new ways to automate production in
his pioneering car assembly plants.
But what is emerging in this fourth wave of
change in industry is ubiquitous sensing,
connectivity and sophisticated control, in all
kinds of devices. This means that designers of
industrial systems are in many cases entering
uncharted territory: many are enjoying their first
encounters with wireless system design, sensor
fusion, energy harvesting, ultra-low power design
and Variable-Speed Drive (VSD) control systems.
These are specialised design disciplines, and
are supported by a huge and varied choice of
products and technologies for implementing
them. That is why Future Electronics has
created dedicated divisions with specialist
know-how in the functions that our customers
will need as they develop equipment for
Industry 4.0.
Today, customers throughout the Europe,
Middle East and Asia region are able to draw on
specialist expertise in power-system design
through the Future Power Solutions division,
and on wireless connectivity expertise through
Future Connectivity Solutions. At Future Power
Solutions, for instance, technology specialists
can help to advise design engineers on the use
of the latest Intelligent Power Modules (IPMs),
which provide a compact, easy-to-use and
complete inverter solution, a core element of a
VSD. They can also explain the applications and
limitations of today’s energy-harvesting solutions.
The experts at Future Connectivity Solutions,
likewise, can help designers to navigate through
the maze of competing radio standards.
Depending on the application, a wireless sensor
node for use in the smart factory of tomorrow
might require one or more radios, with a choice
of NFC, Bluetooth®, Wi-Fi®, ZigBee®, LoRa™,
SIGFOX and other technologies all potentially
suitable. Future Connectivity Solutions can help
to choose the right technology, and find a
choice of components to fit the design
architecture and budget.
Wherever Industry 4.0 is a real phenomenon,
then, and not just a slogan, Future Electronics is
ready to help.
So if you are thinking today about the
development of your next ‘Industry 4.0’ product,
please find inspiration in the pages of FTM, and
ask for practical help from the Future

MOSFET driver helps synchronous-rectification
circuits operate more efficiently
ON SEMICONDUCTOR
The NCP4305 from ON Semiconductor
is a high-performance driver for
controlling a synchronous-rectification
MOSFET in switch-mode power
supplies.
Highly versatile, the NCP4305 may be used in
various topologies, including discontinuouscurrent and continuous-current mode flyback
converters, quasi-resonant flyback converters,
and forward and half-bridge resonant LLC
converters.
The combination of externally adjustable
minimum off-time and on-time blanking
periods helps to mitigate the ringing induced by
the PCB layout and other parasitic elements.
The device’s self-synchronisation feature
ensures reliable and noise-free operation of the
synchronous-rectification circuit.
The NCP4305 also makes use of a Kelvin
connection between the driver and the MOSFET
to achieve efficient operation at full load. Lightload detection also helps the device to
optimise operation for efficiency at light loads.
The precise turn-off threshold, extremely low
turn-off delay time and high sink-current
capability of the driver allow the MOSFET to
maximise its conduction time in synchronousrectification mode for the highest power-supply
efficiency.
The high accuracy of the NCP4305 driver,
and its 5V gate clamp, mean that users of the
NCP4305 can opt to use Gallium Nitride (GaN)
FETs in their power-supply design.

It achieves this with a built-in boost converter
which generates the voltage rail for the output
stage, while using a battery-tracking automatic
gain control to adjust the gain and to limit
battery current when the battery voltage is low,
thus prolonging battery life.
Offering typical efficiency of 85%, the

amplifier compared to a
standard amplifier
connected directly to the
battery.
The PAM8905 features
DC input-voltage protection
to prevent damage to the
speaker should the input

New series of op amps features almost
zero offset and drift
STMICROELECTRONICS
STMicroelectronics’ TSZ12x series of
accurate operational amplifiers offers a
very low input-offset voltage with
almost zero drift.
The TSZ12x CMOS devices
achieve a low offset drift and
eliminate 1/f noise because of
their chopper architecture.
Chopper-stabilised op amps
constantly correct lowfrequency errors across the
inputs of the amplifier.
The offset voltage is rated at
a maximum 5µV at 25°C.
Even over the full temperature
range of -40°C to 125°C, the
offset rises to no more than
8µV. This exceptional accuracy
and stability is combined in
the TSZ12x series with an
excellent speed/power
consumption ratio.
The op amps feature a 400kHz gain-bandwidth
product, while drawing less than 40µA at 5V.
The devices also operate from an ultra-low
input-bias current. These features make the
TSZ12x family ideal for sensor interfaces and
battery-powered applications.
The TSZ121 is the single version, TSZ122
the dual version and the TSZ124 the quad
version. The pin-outs for all three devices are
compatible with industry standards.
The devices can operate from input voltages
ranging from 1.8V to 5.5V. The parameters are
fully specified for 1.8V, 3.3V, and 5V power
supplies, but are very stable across the full

50A power-supply connector offers various safety
and reliability capabilities
HIROSE
Hirose’s EM series of 50A powersupply connectors is ideal for
industrial equipment which requires a
high power rating and durability.
The EM range consists of in-line plugs and
receptacles. The receptacles may be panelmounted or attached to a DIN rail.
The innovative connector design incorporates
three 50A power
contacts and one ground
contact. For safety, the
contacts are arranged in
sequence to ensure that
the ground contact is
connected before the
power contacts during
the mating process. The
connector also has a
protective cover over the
female contacts to
protect the contact area
from the risk of damage.
Termination of the crimp contact is quick and
easy using standard JIS crimping tools. A
contact removal tool is also available.
The connector can withstand high
mechanical stress with up to 200N of vertical
cable pull force being applied safely. The
robust snap-on lock provides secure mating
with an audible tactile click to confirm correct
engagement.
Customised keying arrangements can be
applied to prevent incorrect mating of multiple
connectors. Ten different keying combinations
are possible through optional keys.

How to achieve ‘zero’ stand-by power consumption
in an offline AC-DC converter
STMICROELECTRONICS
Regulations which are in place today, or which are set to come
into force in the near future, are forcing manufacturers of
electronic equipment to reduce stand-by power consumption
in devices sold in almost every developed region of the world.
Many kinds of appliance sit in an idle state most of the time.
Today, they normally waste energy simply because the user
omits to turn off the mechanical switch, leaving the connection
with the mains power line open.
Now, however, there is a solution which solves this problem without
having to change the behaviour of the user: the Zero Power mode in the
VIPer0P, an offline AC-DC converter from STMicroelectronics. Its clever
on/off management enables extremely low input-power consumption
even when appliances are connected to the mains in an idle state.
In fact, as soon as the equipment completes its working cycle, it can
be automatically turned off and immediately switched on again only
when required. The control of the Zero Power mode is automatic with a
microcontroller, or manual using a tactile low-voltage button or remotecontrol system. In fact, thanks to the VIPer0P’s Zero Power mode
mechanical switches can be eliminated, saving bill-of-materials cost.
A simplified block diagram of the VIPer0P converter is shown in
Figure 1. It consists of an 800V MOSFET with on-resistance rated at
20Ω, and a fixed-frequency current-mode PWM controller with overcurrent protection. It operates at a jittered fixed frequency, reducing EMI
filtering requirements.
Fig. 1: Simplified block diagram of the VIPer0P AC-DC converter
Two different part numbers are available: the ‘L’ version is optimised for
a 60kHz switching frequency, and the ‘H’ version for 120kHz. The user
can choose the frequency which best balances efficiency and transformer
size. The VIPer0P is also equipped with a light-load management scheme
which ensures that it achieves good efficiency even when supplying a
load as small as a few milliamps.
In the steady state, the IC supports either self-supply or an external
supply. Since it has a wide input-voltage range of 5-30V, it can operate
from an external supply even when the output voltage is as low as 5V.
The upper limit of 30V accommodates large variations in the auxiliary
voltage, thus giving the user flexibility in the selection of a transformer.
Primary applications for the VIPer0P
AC-DC converter
Zero-Power mode for stand-by operation
A key feature of the VIPer0P IC is its Zero Power mode, an idle state in
which the device is totally shut down, the output voltage is zero, and the
residual power consumption from the mains is kept below 4mW at 230V
AC, as shown in Table 1.

How a new IR sensor grid-on-chip supersedes the
conventional single-element PIR sensor
PANASONIC
The use of MEMS technology has had a remarkable impact on
the development of uncooled Infra-Red (IR) sensors, paving
the way for the introduction of free-standing thermal-isolation
structures with thin-film IR absorbers. New applications are
emerging for this new class of miniature sensors, such as
thermography, human detection, night vision and more.
In fact, IR thermal-sensing and imaging instruments make it possible to
measure and map surface temperature and thermal distribution passively
and non-intrusively. This is because IR radiation is emitted by all objects
with a temperature above absolute zero. For an object that has no
colour – that is, no wavelength is selectively emitted or absorbed – the
radiation spectrum is completely determined by temperature alone. With
rising temperature, the intensity at every wavelength of the radiation
spectrum also increases. This means that it is possible to remotely
determine the temperature of a body or object by measuring its radiated
power.
Now, a new IR detection device, the Grid-EyE sensor array from
Panasonic Automotive and Industrial Systems, uses this capability for
the precise detection of the thermal signature of bodies such as human
beings, as well as inanimate objects, in the array’s field of view.
lens, as shown in Figure 2. It has 64 thermopile elements in an 8x8 grid
format which detect absolute surface temperature by sensing IR
radiation, that is, without contacting the surface.
Unlike conventional
sensors, Grid-EyE
uses a patented 60°
silicon lens etched
out of a silicon wafer,
which is, at less than
0.3mm high, the
smallest lens on the
market. The sensor
package’s size is just
11.6mm x 8mm x
4.3mm, which is
around 70 % smaller
than competing
Fig. 2: The Grid-EyE integrated package
products.
In contrast to
single-element thermopile sensors and pyroelectric sensors, the GridEyE sensor can not only detect moving people and objects but also:
• the position and presence of motionless people and objects
• the direction of movements
• surface temperature from -20°C to 100°C
A comparison of sensing technologies is shown in Figure 3.
The Grid-EyE’s measurements are accurate: Panasonic rates the
Grid-EyE’s Noise-Equivalent Temperature Difference (NETD) at ±0.5°C at
room temperature. Its co-ordinated array of sensing elements can detect
multiple people or inanimate objects moving in different directions. At
close proximity, Grid-EyE is even capable of detecting hand movements
for simple gesture control.

the 8px x 8px Grid-EyE
Fig. 1: The Grid-EyE thermopile sensing elements are fabricated using MEMS technology
IR detector based on advanced MEMS technology
The Grid-EyE sensor array uses MEMS fabrication technology to enable
the implementation of an 8 pixels x 8 pixels IR sensor array in a sensor
die with a footprint of just 3mm x 3mm, as shown in Figure 1. This
technology makes it possible to produce a thermopile type of IR sensor
consisting of hundreds of thermocouples on an area of several square
millimetres. Such a sensor is extremely sensitive and has a very fast
response time.
But it can also be produced at low cost because of its small size, and
the ability to use standard silicon IC fabrication processes to make it in
high volume.
And because the sensor is comprised of an array of sensor pixels,
rather than a single sensing element as in the common pyroelectric type
of IR sensor, it provides for much more sophisticated and valuable
applications than were possible before.
Advantages of the Grid-EYE array sensor
Panasonic’s Grid-EyE IR array sensor is the first ever 64-pixel IR camera
in a compact, integrated surface-mount package. Grid-EyE combines
the MEMS sensor chip, a digital ASIC with an I2C interface, and a silicon
10
The applications for this more sophisticated form of IR sensing are many.
They can include factory automation systems, in which the Grid-EyE
sensor can monitor and count inanimate objects, and equipment
maintenance, since the Grid-EyE sensor can form a thermal image of a
piece of equipment: overheating is a common early-warning sign of a
mechanical malfunction.
The Grid-EyE sensor can also be used in supply-chain equipment, for
instance for monitoring perishable or temperature-sensitive goods. And it
is also ideal for detecting the presence and motion of human beings, for
instance in building-automation and security systems.

to develop sophisticated solutions in the digital
control field.
A joystick on the motor-control kit may be
used to control the speed and direction of the
motor. It is also possible to define a complex
sequence of events, in which the
SCTimer/PWM evolves autonomously through
the state machine over time, in
response to time-based or I/Odefined events.
This means that the system
makes fewer calls on the
CPU, since the
SCTimer/PWM is able to
handle most of the control
sequence in hardware. Using the
SCTimer/PWM also reduces the
application’s code size.
The firmware package available from NXP
implements the motor-control project in the
Keil Integrated Development Environment (IDE)
as well as in the LPCXpresso IDE. The
package also contains an application note
which describes in detail how to control the
motor’s operation using the SCTimer/PWM.

POWER
SUPPLY
STMICROELECTRONICS
STMicroelectronics’ L6599A is a double-ended controller for
use in high-voltage power converters with a series-resonant
half-bridge topology. It provides a 50% complementary duty
cycle: the high-side and low-side switches are driven on and
off 180° out-of-phase for exactly the same time. Output-voltage
regulation is achieved by modulating the
operating frequency.
A fixed dead-time inserted between
the turn-off of one switch and the
turn-on of the other guarantees
soft-switching and enables highfrequency operation.
The IC enables the designer to set
the operating frequency range of the
converter by means of an externally
programmable oscillator.

AMS
ams has introduced the AS5047P, a
magnetic rotary position sensor for
motor and motion-control applications
which offers very high accuracy even
at very high rotation speeds.
The 47 series magnetic sensors’ high-speed
performance and ABI incremental outputs
make them ideal as robust replacements for
optical encoders. The total system cost of a
design based on the 47 series is also normally
far lower than the cost of an equivalent optical
encoder or resolver.
Like other members of the 47 series of
position sensors, the AS5047P features ams’
Dynamic Angle Error Compensation (DAEC™)
technology, which produces outstanding angle
measurement accuracy even at very high
rotation speeds. In the AS5047P, the
maximum rated measurement speed is
28,000rpm, thus enabling it to support many
high-speed rotating-shaft applications that
previously could only be addressed with
optical encoders.

programmable amplifier and a 13-bit
sigma-delta ADC.
The LX3302 also integrates a 32-bit
RISC processor which provides
programmable digital-filtering and signalprocessing functions.
160337:
CENTRE
The DAEC technology in the AS5047P
provides compensation for the dynamic angle
error caused by the propagation delay as the
sensor processes raw measurements of
magnetic field strength. DAEC thus eliminates
the need for system designers to implement
discrete error-correction circuitry in an external
DSP or MCU. With DAEC, the AS5047P
achieves very high accuracy, rated at a
maximum 0.34° at a constant rotation speed
of 28,000rpm (excluding integral non-linearity).
The 47 series’ ABI outputs are equivalent to
the outputs of a standard optical encoder, so
motor-control system designers can easily
replace an optical encoder with an ams
magnetic position sensor measurement
system without any change to their control
software or interface. In the AS5047P, the
maximum resolution of the ABI output is 4,000
steps/1,000 pulses per revolution in decimal
mode, and 4,096 steps/1,024 pulses per
revolution in binary mode.
The device also simultaneously provides a
standard UVW commutation interface for use
in brushless DC motors, eliminating the need
for discrete Hall sensor switches.

New IGBT power modules increase
efficiency and reduce conduction losses
VISHAy
Vishay Intertechnology has introduced
four new half-bridge and single-switch
IGBT power modules intended
specifically for use in Tungsten Inert
Gas (TIG) welding machines.
Built on Vishay’s proprietary ‘Trench PT’ IGBT
technology, the VS-GP100TS60SFPbF,
VS-GP250SA60S, VS-GP300TD60S and
VS-GP400TD60S feature extremely low
collector-to-emitter voltages, reducing
conduction losses and helping to improve the
energy efficiency of the output inverter stage in
welding machines.
Efficiency as well as long-term reliability are
also enhanced by the low turn-off switching
energy required by the modules, which is
around half as much as that of the previous
generation of devices.
Since the Trench PT IGBTs are smaller than
equivalent planar IGBTs, they offer higher
current density and lower thermal resistance
(junction-to-case) without compromising
performance.

Contactless connector system gives freedom of
movement and immunity to dust, dirt and vibration
TE CONNECTIVITy
TE Connectivity™ (TE) has introduced a
family of contactless connectors for
applications in which limitations due to
space restrictions, or exposure to
vibration, dust and dirt, make the use of
traditional contacting connectors
undesirable.
TE’s ARISO™ Contactless
Connectivity platform is a hybrid
interconnection system, based
on contactless power and data
technology, which can easily
connect over a short distance
without a physical connection.
The contactless connectors,
which can replace complex and
expensive harness constructions
and slip rings, are immune to
vibration, pollutants and harsh
environments, and are
unconfined by movement
restrictions.
24
This offers design flexibility while reducing the
time and effort required for maintenance and
installation, and enables developers to designin connectivity in situations in which it was not
possible before.
The ARISO Contactless Connectivity platform
can also be used to easily build on-the-fly
connections, such as when connecting remote
I/Os or sensors on moving machine parts
which require quick connections and
immediate system response.
It also eliminates any limit on the number of
mating cycles in wet or dusty environments,
since it has physically separated coupler ends.

Evaluation kit for infra-red array sensor
enables fast prototyping of IoT applications
PANASONIC
Panasonic Automotive and Industrial
Systems has released an evaluation kit
for wireless sensor development which
includes its Grid-EYE Infra-Red (IR) array
sensor and nanopower PAN1740
Bluetooth® Smart module and a
microcontroller on a single board.
By combining its new IR sensor technology with
Bluetooth technology and software for IR
detection of people and objects on one board,
Panasonic enables users to rapidly develop
prototypes and build new Internet of Things
(IoT) applications.
The kit’s software includes a basic
application-programming interface and imageprocessing capability. Available as both PC
software and a smartphone app, it enables
users to test the sensor in various applications.
The Grid-EyE IR array sensor is the first ever
64-pixel IR camera in a compact surface-mount
package. Based on Panasonic’s MEMS
technology, the Grid-EyE device combines a
MEMS sensor chip, a digital ASIC with an I2C
interface, and a silicon lens just 0.3mm high. It
has 64 thermopile elements in an 8x8 grid
format which detect absolute surface
temperature without any contact.
The sensor package measures just 11.6mm
x 8mm x 4.3mm, which is around 70% smaller
than competing products. It is capable of
detecting the position and presence of people
and objects, whether they are still or moving,
sensing the direction of movement, and
capturing accurate measurements of surface
temperature in a range from -20°C to 100°C.
The PAN1740 Bluetooth module in the kit is
optimised for low-power operation, drawing just
4.9mA in Transmit or Receive modes, and has
a footprint of just 9.0mm x 9.5mm, and is
1.8mm high. It can run from a coin-cell battery.

Intelligent power modules: the latest
product developments, and how designers
can take advantage of them
READ THIS ARTICLE TO FIND OUT ABOUT
By Martin Schiel
Strategic Technical Sales Manager, Future Power Solutions (EMEA)
Worldwide, the move to replace simple fixed-speed motor
drives with more sophisticated Variable-Speed Drives (VSDs)
is rapidly gathering pace. Driven by new regulations, such as
the European Commission’s Energy-related Products (ErP)
directive, manufacturers of electric motors are having to
equip their products with the ability to match their speed and
power output to the load, providing for a huge reduction in
average power consumption.
Indeed, increasing the efficiency of electric motors provides great scope
to reduce both the operating costs and the environmental impact of
energy generation: by installing inverters and high-efficiency motors,
some 43TWh of energy could be saved annually in the European Union
alone (source: Siemens research).
At the heart of all VSDs is a common type of power circuit: an inverter.
A motor’s inverter may be implemented as a discrete circuit made up of
as many as 20 components. Power IC manufacturers, however, have
recently invested heavily in the expansion of their range of Intelligent
Power Modules (IPMs), a component in a single package which
integrates most of the components in an inverter circuit.
In the domains of both RF and power electronics design, the module
is a well known and understood concept. In general, modules offer the
advantages of small size, good performance and ease of use, which are
balanced by the drawbacks of higher unit cost and lack of flexibility.
In their latest generation of products, IPM suppliers are attempting to
swing this balance firmly in their favour by improving the choice of
options available to the designers of VSDs. This article examines the
case for and against the IPM in the light of the latest product
developments.
Why energy efficiency has come to the fore
As part of the European Union’s 20/20 initiative (setting the goal of
reducing CO2 emissions by 20% by 2020), the provisions of the 2009
ErP directive are being steadily tightened. For standard motors with a
power output in the range 0.75kW-375kW, there are four classification
levels: IE1-4, with IE4 requiring the highest efficiency.
Since 2011, all electric motors have been required to be classified at
least at level IE2. From the start of 2015, electric motors in the power
range from 7.5kW-375kW must be at the higher IE3 level, or at IE2 only
if they are a VSD type. This same rule will apply from 2017 onwards
additionally to motors at the lower 0.75kW to 7.5kW power range.
For many OEMs, the best way to meet the requirements of the ErP
directive is to replace legacy fixed-speed motors with a new VSD
design. Many hundreds of new products to be introduced in the next
two years will therefore include a new VSD. Such products include:
Single-phase motors
<100W: pumps, fans, handling devices, compressors
100W-2kW: power tools, white goods, blinds, universal and servo drives
2kW-5kW: heating-system pumps, air-conditioning equipment
Three-phase motors
2kW-20kW: heating-system pumps, air-conditioning equipment,
conveyor systems, universal and servo drives
>20kW: a wide variety of industrial equipment
26
• Changes in European regulations that are pushing OEMs to replace
fixed-speed drive designs with new variable-speed drives
• The benefits of implementing the inverter stage of a variable-speed
drive with an off-the-shelf intelligent power module
• Factors to consider when selecting a supplier of intelligent power
modules
An inverter will be found in every one of these VSD motors, as shown in
Figure 1. And most designers will focus on the following requirements for
the inverter design:
• High efficiency, which helps the motor manufacturer to comply with
regulations such as the ErP directive
• Small size – cutting the motor’s size and weight helps to reduce Bill-ofMaterials (BoM) costs, improves operating efficiency and saves fuel in
transportation equipment, and releases space for other uses. It also
means the motor-control system may be placed closer to the motor,
resulting in reduced EMI and parasitic effects in the PCB.
• High reliability, for long and predictable service life and low recall and
repair costs
Fig. 1: Architecture of a typical variable-speed motor drive (Source: Fairchild)
So how well does an IPM, which is also known as a Smart Power
Module (SPM) or Small Low Losses Intelligent Moulded Module
(SLLIMM), meet these requirements? In fact, all IPMs use the same basic
‘recipe’ of components, as shown in Figure 2. An IPM is comprised of:
• Six power transistors, either IGBTs or MOSFETs
• Six fast-recovery diodes
• Gate-drive ICs
• Gate resistors
• Optional thermistors
• Bootstrap diodes
Some modules also integrate an internal shunt resistor for output-current
measurement whilst others rely on external shunt resistors for this
function. In addition, some module manufacturers integrate noiseabsorbing capacitors or comparators.
When integrated into a module’s single package, an inverter gives the
designer the benefits of reduced size and improved reliability. The board
footprint occupied by a modular solution is around 50% smaller than
that of the equivalent discrete solution, because the module eliminates
the board-level interconnections required between discrete components.

• Fully moulded housings have a lower cost, but worse thermal
performance, and so are restricted to modules with a relatively low
power rating.

Because the module solution reduces the inverter component count
from around 20 to one, reliability is also improved. The risk of failures or
mistakes in the assembly process falls dramatically when the component
count falls. In addition, the number and length of the interconnecting
traces is massively reduced, cutting the inverter system’s susceptibility to
EMI and noise, and providing for more stable, predictable and reliable
performance. The module also eases the design team’s compliance
burden, since it provides a fully pre-tested sub-system, typically
including UL-recognised isolation characteristics.
Other advantages are also available to the user of an IPM. Crucially,
the implementation of an inverter design is far easier, and provides for a
shorter time to market, when using a module. The module will be
supported by full documentation, with verified performance data. In
addition, IPM suppliers provide easy-to-use, free PC-based development
software which helps to accelerate and simplify the configuration of all
the inverter’s parameters.
And of course, the matching of the internal components, and handling
of the parasitics, are dealt with by the module manufacturer. In a discrete
design, the OEM designer must manage these issues.
The module also provides advantages at the production stage: a
circuit with one component rather than 20 is easier and cheaper to
assemble on the board, and the reduction in component count also
streamlines inventory and vendor management.
The case in favour of using a module, then, seems remarkably strong.
And yet many designs today continue to be implemented with discrete
components. This is because OEMs have in the past found two main
drawbacks in modules: inflexibility and cost.
Clearly, the specifications and performance of a module are
determined by the module’s manufacturer – not by its user. And these
specifications might, in theory, not match the user’s requirements
exactly. A discrete design, by contrast, can be made to closely fit the
application.
This argument, however, loses force when applied to inverter
applications. IPMs are intended precisely for use as inverters in VSD
designs, and the IPM suppliers have developed product ranges that
meet the needs of nearly all users, from the 0.75kW to 7.5kW segment
up to high-power motors using >20kW. These varied needs are met by
devices covering a range of breakdown-voltage, peak- and averagecurrent and thermal-dissipation requirements.
In part, the variation in user requirements is met by offering the same
or similar circuits in different package types and sizes, including PQFN,
surface-mount, Single In-Line (SIL) and Dual In-Line (DIP).
IPM manufacturers also tend to develop product variants with different
housing styles, for different power-output ratings:
• Insulated Metal Substrate (IMS) technology is thermally efficient, very
robust and offers an easy means to take temperature measurements
for the protection circuits.
• Direct Bonded Copper (DBC) is a highly thermally efficient technology
which supports higher power densities, as shown in Figure 3.
Aluminium oxide or aluminium nitride ceramic baseplates also provide
high thermal performance at a slightly lower cost.
Manufacturers such as STMicroelectronics, Fairchild and ON
Semiconductor see a great opportunity in the IPM market, and have
been busy introducing new products at a rapid rate. So users now have
a very good chance of finding a module that closely matches the
requirements of their inverter. In addition, for most it is an advantage that
the gate-drive IC is integrated in the module: when the gate driver is
close to the gate of the IGBT or MOSFET, it is less affected by noise,
and consequently operates more reliably and predictably.
Clearly the integration of the gate driver removes from the user the
freedom to control the gate-drive voltage directly, and for a very small
number of motor-control designers, this restriction might be of some
importance. For most, it is an advantage not to have to match the gatedrive circuit with the power transistor.
The second commonly cited, and important, objection to the use of
an IPM is on the grounds of cost: the unit BoM cost of a module is
usually higher than the aggregated BoM cost of the discrete
components that it replaces.
Experienced users of modules, however, tend to disregard
comparisons of unit BoM costs. This is because the metric that matters
is the total cost, not simply the aggregated BoM cost. And when that is
taken into account the module will win more often than not.
As described above, the IPM offers size and reliability advantages
because it is a single, highly integrated component that may be used in
place of around 20 discrete components. This also provides great cost
advantages:
• The circuit design is easier, quicker and therefore cheaper to
implement
• Board assembly is quicker and easier, so production costs and
wastage are lower
• The module’s board footprint is smaller, so the PCB is smaller and
cheaper
• Lower component count results in higher reliability, for lower
maintenance, repair and recall costs
• The module’s reduced susceptibility to EMI eliminates any requirement,
in a discrete design, for costly EMI counter-measures and materials
When all costs over the lifetime of the motor – including design, BoM,
production and after-sales costs – are taken into account, the modular
solution can in many cases be the cheaper one. Perhaps more
importantly, it is also the solution with the more predictable and lower
financial risk across the project lifecycle.
How to make module choices
For all except high-volume applications in which BoM cost is by far the
greatest contributor to total cost, then, an IPM is a highly attractive
choice for designers implementing a motor drive’s inverter circuit.
The choice of IPMs and of IPM suppliers is wide. Since IPMs are
produced in standard ratings and package styles, the differences
between one similarly rated module and another are in most cases
small. The choice of IPM supplier can then seem difficult to make.
For some applications, a particular feature or specification of one
module over another – such as a small advantage in terms of efficiency
at light loads, for instance, or a slightly superior thermal dissipation rating
– might be important. For many, the specifications of rival modules will
not be decisive.
In all cases, however, it is important to remember the advantage of
modules as described above: unlike a yet-to-be-designed discrete
circuit, a module offers clearly documented and verified performance.
The user must be able to trust absolutely the quality and performance of
the module he or she chooses. And this means that the only golden rule
when choosing a module supplier is to select a company with an
excellent track record in the power semiconductor market, and with a
strong reputation to protect.
On these grounds, Future Power Solutions is happy to recommend
ON Semiconductor, STMicroelectronics and Fairchild as proven and
trusted IPM suppliers.
