Programmable DC Power Supply
CINERGIA’s DC converters are power electronics devices designed
to generate a DC constant voltage, current, power, resistance or IU
battery charge profile. Our DC products (DCPS, EL-DC, B2C) differ
in the possible operation modes.
Thanks to its bidirectional power hardware, the test energy can be
regenerated to the electrical grid.
FUNCTIONAL DESCRIPTION
KEY FEATURES
Operation modes:
-Constant Voltage (CV)
-Constant Current (CC)
-Constant Power (CP)
-Automatic test from csv file
6.75 – 160 kW
Three DC channels in each unit:
The three channels can be controlled independently
allowing different voltage, current or power setpoints.
In standard units the Operation mode will be the same for
the three channels. Optionally, each channel could be
operated in different mode (if interested, please ask for
option Independent Channels Operation).
2Q or 4Q applications:
-In 2Q applications, the EUT will be connected between
one channel and the common negative.
-In 4Q applications, the EUT will be connected between
two channels

BACK-TO-BACK TOPOLOGY
The equipment is formed by two IGBT-based power stages: a grid-side Active Rectifier producing
sinusoidal currents with low harmonic distortion and close to unity power factor; and three output DCDC
converters generating three independent DC channels.
Thanks to the bidirectionality of this topology the test energy can be injected back to the grid.

AC Input is connected to the grid (isolation transformer with neutral is recommended)
DC Output is connected to the Equipment Under Test (EUT) and can be used as:
- Independent channels mode: three 2Q channels with a common negative
- Parallel channels mode: one 2Q channel (3 times rated current per phase)
- One 4Q bipolar channel (connecting the load between two channels)
- One +270/0/-270V channels for avionics applications

Output current (A)
In UNIPOLAR the equipment under test is connected between a
channel and the common negative. Two possible configurations:
DCPS_2016_v1
Independent channels: CH1, CH2 and CH3 are available and can
be parametrized with different voltage, current or power
setpoint.
-400.0
Output current (A)
In BIPOLAR the equipment under test is connected between
channels CH1, CH2 and CH3. The common negative is not
connected and CH2 is used as 0V reference for CH1 and CH3.
This connection will be used to create +270V/0/-270V avionics
DC bus system.
Parallelized channels: the three channels are “shortcircuited”
internally to provide three times the current.
Maximum voltage in bipolar connection is ±350V. Ask for further
information if ±750V are needed.
Cooling
The power supply is air-cooled internally.
