Dual motor control and PFC demonstration board featuring the STM32F103 and STGIPS20C60
  • active Active

The STEVAL-IHM034V2 is a complete motor control kit solution for the evaluation of STMicroelectronics® wide product portfolio tailored to applications where it is necessary to 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) v3.2 or later and its compatible PFC v1.0 firmware plug-in.
