STMicroelectronics STEVAL-IHM028V2

Overview

STEVAL-IHM028V2 from STMicroelectronics is a fully populated 2 kW, 3-phase motor control evaluation board built around the STGIPS20C60 600 V / 17 A IGBT intelligent power module (IPM), supporting field-oriented control (FOC) with hardware-based current sensing, overtemperature/overcurrent protection, and active fan cooling. It accepts 90–285 VAC or 125–400 VDC input, includes PFC-compliant +400 V DC bus support, inrush limiter with bypass relay, and tachometer/Hall/encoder interface.

For engineers reviewing the STEVAL-IHM028V2 datasheet, STEVAL-IHM028V2 pinout, STEVAL-IHM028V2 application, or STEVAL-IHM028V2 equivalent, this board delivers validated hardware for rapid FOC algorithm development, thermal management validation, and three-shunt or single-shunt current sensing topology evaluation in high-efficiency motor drives.

Technical Context

The board implements a complete 3-phase inverter stage using the STGIPS20C60 IPM, which integrates six IGBTs with negative temperature coefficient, bootstrap gate drivers, undervoltage lockout, and smart shutdown logic. Its analog front-end supports both Hall-effect sensors and incremental encoders for rotor position feedback.

Hardware protection includes dedicated overvoltage comparator for brake function, discrete overtemperature monitoring with automatic fan activation, and fast-response overcurrent detection via shunt resistors. The buck converter (VIPer26LD) generates isolated +15 V and +3.3 V rails for microcontroller and gate driver supply.

FAQ

Does STEVAL-IHM028V2 support sensorless FOC?

No-it requires rotor position feedback via Hall sensors or incremental encoders, as confirmed by its dedicated J5 (Hall) and J6 (encoder) headers and absence of back-EMF sensing circuitry. The board lacks line-voltage sampling or high-frequency injection paths needed for sensorless operation.

What microcontroller interface does it use?

The board provides standard 3.3 V logic-level signals compatible with STM32 MCUs (e.g., STM32F3/F4 series), including PWM inputs, enable/disable lines, fault flags, and analog current feedback outputs-no level-shifting required for ST's Cortex-M based motor control kits.

Can it operate from a 400 V DC bus without modification?

Yes-the design explicitly extends the input voltage range to +400 V DC for PFC compliance, verified by capacitor ratings (C1/C2: 450 V), IPM maximum collector-emitter voltage (600 V), and bus voltage divider scaling in the schematic (R10/R11).

Is the STGIPS20C60 IPM replaceable with another module?

No-the board is mechanically and electrically optimized for STGIPS20C60, including footprint, gate drive layout, thermal pad alignment, and protection thresholds. Substitution would require PCB redesign, gate resistor recalibration, and revalidation of short-circuit ruggedness timing.
