EVSPIN32F06Q1S3: 3-phase 3 shunt inverter based on STSPIN32F0601
Introduction
The EVSPIN32F06Q1S3 board is a 3-phase complete inverter based on the STSPIN32F0601Q 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 Safety and operating instructions
2.1 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.
UM2835
Safety and operating instructions
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.
Attention: 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.
Important:
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.
2.2 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.
2.3 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).
2.4 Operating the evaluation board
To operate properly the board, follow these safety rules:
UM2835 - Rev 1
page 3/19
Operating the evaluation board
1. Work Area Safety:
– 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 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.
UM2835
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.

Board description
6.3
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 STSPIN32F0601Q 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 EVSPIN32F06Q1S3 evaluation board implements overcurrent protection based on the STSPIN32F0601Q
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.
