STMicroelectronics STEVAL-IPM10F

Overview

STEVAL-IPM10F from STMicroelectronics is a compact, RoHS-compliant motor drive power evaluation board built around the STGIF10CH60TS-L SLLIMM™ 2nd series intelligent power module. It delivers up to 1000 W output at 6 A nominal current, supports 125–400 VDC input, and integrates hardware overcurrent protection, NTC-based IPM temperature monitoring, and dual current-sensing options (dedicated op-amps or MCU-embedded) for field-oriented control (FOC) of 3-phase motors in white goods and HVAC compressors.

For engineers reviewing the STEVAL-IPM10F datasheet, STEVAL-IPM10F pinout, STEVAL-IPM10F application, or STEVAL-IPM10F equivalent, this board provides verified interface compatibility with STM32-based control boards, validated three-shunt and single-shunt configurations, Hall/encoder input support, and fault signaling via EM_STOP and TSO pins - all critical for rapid FOC prototyping and inverter validation.

Technical Context

The board implements a 3-phase inverter stage using the STGIF10CH60TS-L IPM, which integrates six 600 V, 10 A IGBTs with integrated gate drivers, bootstrap diodes, undervoltage lockout, and thermal shutdown. Its sensing architecture supports both isolated shunt-based current measurement (via TSV994 op-amps) and direct MCU ADC interfacing, enabling precise phase current reconstruction.

Control interface is standardized via a 32-pin motor control connector supporting PWM-H/L signals per phase, bus voltage feedback, NTC thermistor input, and fault reporting (SD, TSO). The board's universal breadboard-compatible layout includes test points (TP1–TP26), jumper-selectable shunt configuration (SW1–SW4), and encoder/Hall sensor termination (J5) - all designed to decouple power stage evaluation from controller selection.

FAQ

Does STEVAL-IPM10F require an external power supply for the control logic?

No. The board derives 3.3 V and 5 V for control circuitry from the main DC bus via internal LDOs and auxiliary regulators. An external 15 V supply (J4) powers the IPM gate drivers' bootstrap circuitry, but no separate low-voltage control rail is needed beyond the 32-pin interface connection to an STM32 board.

Can STEVAL-IPM10F operate with sensorless FOC algorithms?

Yes. While it includes Hall/encoder inputs (J5), the board fully supports sensorless operation via back-EMF or high-frequency injection methods. Its precise current sensing (±1% gain error, 100 kHz bandwidth per TSV994 channel) and low-latency fault signaling enable robust observer-based position estimation on compatible STM32 MCUs.

What is the role of the TSO pin on the STGIF10CH60TS-L module?

The TSO (Temperature Sense Output) pin provides an analog voltage proportional to the IPM die temperature, scaled to 10 mV/°C. On STEVAL-IPM10F, it connects directly to an ADC input on the control board, allowing real-time thermal derating and safe operating area (SOA) monitoring without discrete NTC calibration.

Is the STEVAL-IPM10F compatible with STM32G4 or STM32H7 series MCUs?

Yes. The 32-pin motor control connector matches the pinout and signal timing requirements of STM32G4 and STM32H7 motor control NUCLEO boards (e.g., NUCLEO-G431RB with X-NUCLEO-IHM07M1). All PWM, current sense, and fault signals meet the electrical specifications defined in ST's AN4695 and UM1912 application notes.
