STMicroelectronics STEVAL-IHM036V1

Overview

STEVAL-IHM036V1 from STMicroelectronics is a low-power 3-phase motor control demonstration board built around the SLLIMM™ intelligent power module STGIPN3H60 (600 V, 3 A IGBT-based inverter bridge) and STM32F100C6T6B ARM Cortex-M3 MCU. It delivers up to 100 W output with AC input 90–285 V or DC 125–400 V, features single-shunt current sensing, hardware overtemperature/overcurrent protection, and supports field-oriented control (FOC) implementation.

For engineers reviewing the STEVAL-IHM036V1 datasheet, STEVAL-IHM036V1 pinout, STEVAL-IHM036V1 application, or STEVAL-IHM036V1 equivalent, this board serves as a fully tested reference for compact, safe, RoHS-compliant 3-phase inverter design targeting appliance motor drives, fan controllers, and small industrial pumps requiring fast current feedback and integrated protection.

Technical Context

The board implements a complete 3-phase inverter stage using the STGIPN3H60 SLLIMM™ module, which integrates six IGBTs with short-circuit ruggedness, negative temperature coefficient behavior, undervoltage lockout, and smart shutdown. Its gate drivers are internally matched and thermally coupled to the IGBTs.

The STM32F100C6T6B MCU provides real-time FOC execution via its 24 MHz CPU, embedded ADC for single-shunt current reconstruction, PWM timers with dead-time insertion, and GPIOs for status monitoring and control. The analog front-end includes dedicated op-amps and comparators for fast overcurrent detection.

FAQ

What motor types is STEVAL-IHM036V1 designed to drive?

The board is optimized for 3-phase brushless DC (BLDC) and permanent magnet synchronous motors (PMSM) rated up to 100 W, with typical use cases including refrigerator compressors, washing machine drum drives, and inline duct fans. Its STGIPN3H60 module supports 600 V blocking voltage and 3 A continuous current, matching common small-appliance motor electrical profiles.

Does STEVAL-IHM036V1 support field-oriented control out of the box?

Yes-it includes full hardware and firmware support for FOC: the STM32F100C6T6B runs pre-integrated motor control libraries, and the single-shunt current sensing circuitry with synchronized ADC sampling enables accurate phase current reconstruction. ST provides the X-CUBE-MCSDK software package with ready-to-deploy FOC examples specifically validated on this board.

Can the board operate from DC bus input only?

Yes-the power stage accepts direct DC input from 125 V to 400 V, bypassing the onboard rectifier. Jumper JP1 allows selection between AC-fed (via bridge rectifier) and DC-fed operation. This flexibility supports integration into existing DC-link systems such as solar inverters or battery-powered equipment.

Are test points accessible for oscilloscope probing of critical signals?

Yes-the board includes labeled test points for all three phase outputs (U/V/W), DC bus voltage, shunt resistor differential voltage, MCU debug interface (SWD), and temperature sensor output. These facilitate real-time validation of PWM timing, current waveforms, fault response latency, and thermal behavior during lab evaluation and tuning.
