3-phase motor control demonstration board featuring IGBT
Introduction
This document describes the 1 kW 3-phase motor control demonstration board, featuring
the STGIPS10K60A: 600 V - 10 A IGBT Intelligent power module. The demonstration board
is a 3-phase inverter for driving an induction motor or PMSM motors up to 1000 W. The main
target of this application is to show users the performance of the ST 25L-SDIP (25-lead,
small dual inline package), IPM - STGIPS10K60A.
The board has been designed to be compatible with a single-phase supply from 90 VAC to
220 VAC, or for DC voltage from 125 VDC to 350 VDC. The document is associated with the
release of the STEVAL-IHM027V1 demonstration board (see
