STEVAL-IHM028V1 2kW 三相马达控制板

This document describes the 2 kW 3-phase motor control demonstration board featuring the IGBT intelligent power module STGIPS20K60. The demonstration board is an AC-DC inverter that generates a 3-phase waveform for driving 3-phase motors such as induction motors or permanent magnet synchronous motors (PMSM) up to maximal 2000 W with or without sensors.

The main device presented in this user manual is a universal, fully evaluated and populated design consisting of a 3-phase inverter bridge based on the 600 V IGBT power module in the SDIP 25L package mounted on a heatsink. The IGBT power module integrates all power IGBT switches with freewheeling diodes together with high voltage gate drivers. Thanks to this integrated module, the system has been specifically designed to achieve power inversion in a reliable and compact design. Such integration saves PCB space occupation and assembly costs, together with high reliability due to the design simplicity.

The board is designed to be compatible with single-phase mains, supplying from 90 VAC to 285 VAC or from 125 VDC up to 400 VDC for the DC voltage.
