EVSPIN32F06Q1S1: 3-phase inverter based on STSPIN32F0601

Introduction

The EVSPIN32F06Q1S1 board is a 3-phase complete inverter based on the STSPIN32F0601Q controller, which embeds a 3-phase 600 V gate driver and a Cortex®‑

populated with any IGBT or power MOSFET in DPAK or power FLAT 8x8 HV package. The board has a single-shunt sensing topology, and both sensored/sensorless FOC and 6-step control algorithms 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.

UM2820

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. T in the documentation and should be strictly observed.

echnical data and information concerning the power supply conditions are detailed

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:

UM2820 - Rev 1

page 3/19

Page 4

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 EL range, a proper insulation method such as a USB isolator must be used to operate the board.

UM2820

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.

6.3 Overcurrent detection and current sensing measurement

The EVSPIN32F06Q1S1 evaluation board implements overcurrent protection based on the STSPIN32F0601Q integrated comparator to load current to CIN pin (TP13). 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.

. The single-shunt resistor measures the load current bringing the voltage signal associated

Bus voltage circuit

By default, the evaluation board has an overcurrent threshold set to I detection of ~560 µs

Overcurrent threshold can be modified changing R33 bias resistor, R38 loop resistor and R34, R36 shunt resistors according to the following formulas:

REF

The output disable time can be monitored on the OD pin (TP12) and is determined mainly by the time required to recharge C18 capacitor up to V

6.4 Bus voltage circuit

The EVSPIN32F06Q1S1 evaluation board provides the bus voltage sensing. This signal is set through a voltage divider from motor supply voltage (VBUS) (R67, R69 and R78, R80), and sent to PB0 GPIO (channel 8 of the ADC) of the embedded MCU.

•

JP6 closed (by default) allows to set the bus voltage divider to 145

• JP6 open allows to set the bus voltage divider to 126
