STEVAL-IHM034V2 dual motor control and PFC demonstration
board featuring the STM32F103RC and STGIPS20C60
Introduction
The STEVAL-IHM034V2 is a complete motor control kit solution, for the evaluation of
STMicroelectronics wide product portfolio targeted at applications where it is necessary to
simultaneously drive 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 application is in room air conditioners (RACs), where this solution can
drive the compressor, the outdoor fan, and the PFC.
The microcontroller unit is the STMicroelectronics ARM™ Cortex-M3 core-based
STM32F103RC, which is able to simultaneously carry out all the above mentioned tasks.
The board is compatible for use 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 by means of the STEVAL-IHM021V2, STEVAL-
IHM024V1, STEVAL-IHM032V1, or STEVAL-IHM035V2.
Simultaneously, the same microcontroller unit drives the onboard boost PFC stage,
designed with the STGW35HF60W ultrafast IGBT and the STTH15R06 Turbo2 ultrafast
diode.
The STEVAL-IHM034V2 can be used together with the STM32 permanent magnet
synchronous motors (PMSM) single/dual FOC software development kit (SDK) v3.2, and
successive versions, and its compatible PFC firmware v1.0 plug-in, and successive
versions. This user manual provides information on using the STEVAL-IHM034V2 board
and its hardware features.
