STMicroelectronics STEVAL-IHM045V1

Overview

STEVAL-IHM045V1 from STMicroelectronics is a 3-phase high-voltage inverter power board designed for field-oriented control (FOC) of PMSM motors, based on the STGIPN3H60A SLLIMM™-nano IPM and VIPer06 offline converter. It supports 30–270 Vac input, delivers up to 100 W at 230 Vac, and integrates hardware overcurrent detection, temperature sensing, Hall/encoder interfaces, and selectable single- or three-shunt current sampling with fast op-amps.

For engineers reviewing the STEVAL-IHM045V1 datasheet, STEVAL-IHM045V1 pinout, STEVAL-IHM045V1 application, or STEVAL-IHM045V1 equivalent, this evaluation board enables rapid validation of sensorless and sensored FOC motor control algorithms using STM32 microcontroller evaluation platforms - especially where precise current feedback, DC bus monitoring, and dual-supply (15 V / 3.3 V) generation are required.

Technical Context

The board implements a complete 3-phase inverter stage using the STGIPN3H60A - a 3 A / 600 V SLLIMM™-nano intelligent power module integrating gate drivers, bootstrap diodes, and protection circuitry. Its IGBT-based bridge operates with integrated shoot-through prevention and thermal shutdown.

An auxiliary power supply built around the VIPer06 fixed-frequency offline controller generates regulated +15 V (for gate driving and analog circuitry) and +3.3 V (for MCU interface), supporting direct connection to AC mains (110/230 Vac) without external adapters. Current feedback paths use TSV994IPT op-amps and TS374CDT comparators for fast shunt-based sampling with configurable topology.

FAQ

What microcontrollers is STEVAL-IHM045V1 compatible with?

The board features a dedicated connector supporting direct interfacing with multiple STM32 evaluation boards including STM3210B-EVAL, STM32100B-EVAL, STM3210E-EVAL, STM3220G-EVAL, STM32303C-EVAL, STM3240G-EVAL, STEVAL-IHM022V1, STEVAL-IHM039V1, and STEVAL-IHM033V1 - all using standard 100-pin or 144-pin expansion headers.

Does STEVAL-IHM045V1 support sensorless FOC?

Yes - the board provides all necessary analog signal conditioning (bus voltage, phase currents, temperature) and digital interface signals required for sensorless FOC algorithms. Its three-shunt current sensing topology and fast op-amp stages enable accurate back-EMF estimation without Hall or encoder inputs.

Can STEVAL-IHM045V1 operate from 110 Vac input?

Yes - the input stage accepts 30–270 Vac, covering both 110 Vac and 230 Vac mains. The VIPer06-based auxiliary supply automatically adapts across this range, maintaining stable +15 V and +3.3 V outputs without manual configuration or component changes.

Is external 15 V power input supported?

Yes - J8 is a dedicated 2-pin connector accepting an external +15 V DC supply, bypassing the onboard VIPer06 AC/DC stage. This allows operation from bench supplies or battery sources while retaining full inverter functionality and protection features.
