Description

The STEVAL-IHM034V2 is a complete motor control kit solution for the evaluation of

drive, simultaneously, two motors in sensorless field oriented control (FOC) and perform

active power factor correction (PFC) through digital control of a single-stage boost DC-DC

converter.

Typical applications include in-room air conditioners (RACs), where this ST solution can

drive the compressor, outdoor fans and PFCs. The microcontroller unit consists of

STMicroelectronics’ ARM™ Cortex-M3 core-based STM32F103RC, which is capable of

carrying out all of the previously-mentioned tasks simultaneously. The board is compatible

with the STM32F2 series and with the ARM™ Cortex-M4 core-based STM32F4 series.

Motor 1 is powered by the onboard SLLIMM™ (small low-loss intelligent molded module)

STGIPS20C60. Motor 2 can be powered by an external STMicroelectronics power stage,

such as those that can be evaluated using the STEVAL-IHM021V1, STEVAL-IHM024V1,

STEVAL-IHM032V1 or STEVAL-IHM035V1 evaluation boards. Simultaneously, the same

microcontroller unit drives the onboard boost PFC stage designed with the STGW35HF60W

ultrafast IGBT or, alternatively, for high switching frequencies the STW38N65M5 MDmesh V

Power MOSFET, and STTH15R06D Turbo2 ultrafast diode or the STPSC1206D Schottky

silicon carbide diode.

The STEVAL-IHM034V2 can be used together with the STM32 permanent magnet

synchronous motor (PMSM) single/dual FOC software development kit (SDK) and its

compatible PFC firmware plug-in.
