STMicroelectronics STEVAL-IHM027V1

Overview

STEVAL-IHM027V1 from STMicroelectronics is a fully-populated 1 kW, 3-phase AC/DC inverter demonstration board built around the STGIPS10K60A 600 V, 10 A intelligent power module (IPM) in a 25-lead SDIP package. It supports 90–220 VAC or 125–350 VDC input, delivers up to 1000 W motor output, and integrates regenerative brake control, inrush current limiting, and a +15 V buck-based auxiliary supply using VIPer16 - designed for PMSM and induction motor control evaluation.

For engineers reviewing the STEVAL-IHM027V1 datasheet, STEVAL-IHM027V1 pinout, STEVAL-IHM027V1 application, or STEVAL-IHM027V1 equivalent, key selection considerations include compatibility with STM3210B-EVAL and other ST motor control kits, tachometer/Hall/encoder interface support, BEMF daughterboard readiness for sensorless BLDC six-step control, and RoHS-compliant construction.

Technical Context

The board implements a three-phase voltage-source inverter topology with integrated gate driving, protection, and current sensing. Its core IPM integrates six IGBTs with bootstrap-fed high-side drivers, under-voltage lockout, overcurrent shutdown, and thermal monitoring - all housed in a single 25-pin SDIP package.

Power stage design includes an active inrush limiter with bypass relay, regenerative braking circuitry tied to DC bus voltage feedback, and isolated current measurement per phase via shunt resistors and operational amplifiers feeding analog outputs for controller ADC sampling.

FAQ

Is STEVAL-IHM027V1 still in production?

No - STEVAL-IHM027V1 is marked as Obsolete in ST's official documentation (Doc ID 17826 Rev 2). It remains available through authorized distributors and Aetrix Electronics for legacy design support, repair, and educational use, but no new revisions or long-term supply guarantees apply.

What controller boards is it compatible with?

It is explicitly designed for interoperability with the STM3210B-EVAL evaluation board and other ST motor control-dedicated kits. The MC connector provides standardized signal routing for PWM inputs, current sense outputs, Hall/tachometer feedback, and enable/fault signals aligned with ST's motor control firmware libraries.

Does it support sensorless BLDC control?

Yes - the board includes dedicated test points and interface provisions for attaching ST's BEMF daughterboard, enabling sensorless six-step commutation of BLDC motors using back-EMF zero-crossing detection without Hall sensors or encoders.

Can the +15 V auxiliary supply be used externally?

Yes - the +15 V rail generated by the VIPer16-based buck converter is accessible via test points and can power external logic, level shifters, or isolated communication interfaces, provided total load remains within the 1 A rating and does not compromise IPM gate drive stability.
