STMicroelectronics STEVAL-IHM032V1

Overview

STEVAL-IHM032V1 from STMicroelectronics is a 3-phase inverter demonstration board supporting both field-oriented control (FOC) of PMSM motors and trapezoidal BLDC motor control, with 150 W output at 230 Vac input, L639x gate drivers, STGD3HF60HD IGBTs, and single-shunt current sensing topology.

For engineers reviewing the STEVAL-IHM032V1 datasheet, STEVAL-IHM032V1 pinout, STEVAL-IHM032V1 application, or STEVAL-IHM032V1 equivalent, this board enables rapid validation of sensorless/sensored motor control algorithms, hardware-level overcurrent protection with boost capability, BEMF detection networks, and seamless interfacing with STM32-based evaluation platforms including STM3210xx-EVAL, STEVAL-IHM022V1, and STEVAL-IHM033V1.

Technical Context

The board implements a full-bridge 3-phase inverter stage using six STGD3HF60HD 4.5 A / 600 V fast IGBTs in DPAK packages, driven by dual L6392D high-voltage gate drivers and one L6391D for bootstrap management. It supports both sinusoidal FOC and trapezoidal scalar control via configurable jumper settings and external reference inputs.

Current feedback uses a single-shunt topology with fast op-amps (U2, U4, U3) featuring offset insertion for bipolar current measurement, while hardware overcurrent protection integrates active boost circuitry and emergency shutdown signaling. BEMF detection, Hall/encoder interface, and temperature monitoring via NTC are implemented as dedicated analog front-end paths.

FAQ

Does STEVAL-IHM032V1 support sensorless BLDC control?

Yes, it supports sensorless trapezoidal BLDC control using the integrated BEMF-detection network, which conditions back-EMF signals for zero-crossing detection and commutation timing without Hall sensors or encoders.

What microcontroller evaluation boards is STEVAL-IHM032V1 compatible with?

It interfaces directly with STM3210xx-EVAL, STEVAL-IHM022V1 (dual-motor STM32F103ZE board), and STEVAL-IHM033V1 (STM32F100-based control stage) via a dedicated 3-pin connector supporting current reference, limitation, method selection, and current boost functions.

Can STEVAL-IHM032V1 operate from 110 Vac input?

Yes, the board accepts wide-range AC mains input (110 Vac and 230 Vac) through its AC/DC power supply stage based on the VIPer12A-E flyback controller, which generates regulated +15 V and +3.3 V rails regardless of input voltage.

Is hardware overcurrent protection adjustable?

Yes, the board implements hardware overcurrent protection with active boost capability - threshold and response behavior can be tuned via external resistor networks (e.g., R67, R64) connected to the L6392D op-amp inputs, enabling configurable trip levels and recovery timing.
