EVSPIN32F0601S3: 3-phase 3 shunts inverter based on STSPIN32F0601
Introduction
The EVSPIN32F0601S3 board is a 3-phase complete inverter based on the STSPIN32F0601 controller, which embeds a
3 ‑ phase 600 V gate driver and a Cortex ® -M0 STM32 MCU. The power stage features STGD6M65DF2 IGBTs, but can be populated with any IGBT or Power MOSFET in DPAK or powerFLAT 8x8 HV package. The board has a three-shunt sensing topology, and the sensored or sensorless field-oriented control (FOC) can be implemented. This allows driving permanent magnet synchronous motors (PMSMs) and brushless DC (BLDC) motors.
It provides an easy-to-use solution for the evaluation of the device in different applications such as refrigerator compressors, pumps, fans and industrial appliances.
The evaluation board is compatible with a wide range of input voltage and includes a power supply stage with the VIPER06XS in flyback configuration to generate +15 V and +3.3 V supply voltages required by the application.
Debug and configuration of FW can be performed with standard STM32 tools through the detachable STLINK debugger. SWD and UART TX RX connectors are also available.

2.4
General terms
Warning:
During assembly, testing, and operation, the evaluation board poses several inherent hazards, including bare wires, moving or rotating parts and hot surfaces.
Danger:
There is danger of serious personal injury, property damage or death due to electrical shock and burn hazards if the kit or components are improperly used or installed incorrectly.
The kit is not electrically isolated from the high-voltage supply AC/DC input. The evaluation board is directly linked to the mains voltage. No insulation is ensured between the accessible parts and the high voltage. All measuring equipment must be isolated from the mains before powering the board. When using an oscilloscope with the demo, it must be isolated from the AC line. This prevents shock from occurring as a result of touching any single point in the circuit, but does NOT prevent shock when touching two or more points in the circuit.
All operations involving transportation, installation and use, and maintenance must be performed by skilled technical personnel able to understand and implement national accident prevention regulations. For the purposes of these basic safety instructions, “skilled technical personnel” are suitably qualified people who are familiar with the installation, use and maintenance of power electronic systems.
Intended use of evaluation board
The evaluation board is designed for demonstration purposes only, and must not be used for electrical installations or machinery. Technical data and information concerning the power supply conditions are detailed in the documentation and should be strictly observed.
Installing the evaluation board
•
•
•
•
The installation and cooling of the evaluation board must be in accordance with the specifications and target application.
The motor drive converters must be protected against excessive strain. In particular, components should not be bent or isolating distances altered during transportation or handling.
No contact must be made with other electronic components and contacts.
The board contains electrostatically-sensitive components that are prone to damage if used incorrectly. Do not mechanically damage or destroy the electrical components (potential health risks).
Operating the evaluation board
To operate properly the board, follow these safety rules.
1. Work Area Safety:
UM2596 - Rev 1 page 3/19
UM2596 - Rev 1
UM2596
Operating the evaluation board
•
•
•
•
The work area must be clean and tidy.
Do not work alone when boards are energized.
Protect against inadvertent access to the area where the board is energized using suitable barriers and signs.
A system architecture that supplies power to the evaluation board must be equipped with additional control and protective devices in accordance with the applicable safety requirements (i.e., compliance with technical equipment and accident prevention rules).
Use a non-conductive and stable work surface.
Use adequately insulated clamps and wires to attach measurement probes and instruments.
•
•
2. Electrical Safety:
• Remove power supply from the board and electrical loads before performing any electrical measurement.
•
•
Proceed with the arrangement of measurement setup, wiring or configuration paying attention to high voltage sections.
Once the setup is complete, energize the board.
Danger:
Do not touch the evaluation board when it is energized or immediately after it has been disconnected from the voltage supply as several parts and power terminals containing potentially energized capacitors need time to discharge.
Do not touch the boards after disconnection from the voltage supply as several parts like heat sinks and transformers may still be very hot.
The kit is not electrically isolated from the AC/DC input. The USB interface of the board does not insulate host computer from high voltage. When the board is supplied at a voltage outside the ELV range, a proper insulation method such as a USB isolator must be used to operate the board.
3. Personal Safety
• Always wear suitable personal protective equipment such as, for example, insulating gloves and safety glasses.
• Take adequate precautions and install the board in such a way to prevent accidental touch. Use protective shields such as, for example, insulating box with interlocks if necessary.

•
•
A protection resistor of 1.8 kΩ is mounted in series with sensor outputs.
For sensors requiring external pull-up, three 10 kΩ resistors are already mounted on the output lines and connected to VDD voltage when JP2 is closed.
The jumper JP7 selects the power supply for sensor supply voltage:
• JP7 pins 1-2 CLOSED : Hall sensors powered by VDD ( 3.3 V )
JP7 pins 2-3 CLOSED : Hall sensors powered by VCC ( 15 V )
JP7 pins 2-4 CLOSED : Hall sensors powered by V5_Hall (+5 V)
•
•
The MCU of STSPIN32F0601 can decode Hall/Encoder sensor outputs configuring jumpers as follows:
• JP3 CLOSED, PA0 connected to Hall1
JP4 CLOSED, PA1 connected to Hall2
JP5 CLOSED, PA2 connected to Hall3
Overcurrent detection and current sensing measurement
The EVSPIN32F0601S3 evaluation board implements overcurrent protection based on the STSPIN32F0601 integrated comparator. The shunt resistors measures the load current bringing the voltage signal associated to load current to the CIN pin (TP29). When the peak current in the phases exceeds the selected threshold, the integrated comparator is triggered and all the power switches are disabled. Power switches are enabled again when the current falls below the threshold and the output disable time expires, thus implementing a current limitation control.
