2 kW 3-phase motor control STEVAL-IHM028V1 demonstration board
featuring the IGBT intelligent power module STGIPS20K60

Introduction
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.
This document is associated with the release of the STEVAL-IHM028V1 demonstration
board (see

Page 16: Circuit Description
Board description UM1036 Circuit description 3.3.1 Power supply The power supply for the STEVAL-IHM028V1 demonstration board is implemented as a wide range converter. The range of the input voltage is from 90 VAC or 125 VDC up to 285 VAC or 400 VDC. This range allows the demonstration board to be used in direct connection with various single phases as well as the PFC input stage. -
Page 17: Inrush Limitation
UM1036 Board description 3.3.2 Inrush limitation The input stage of the demonstration board is provided with an NTC resistor to eliminate input inrush current peak during the charging of the bulk capacitors. To achieve a higher efficiency of the inverter it is possible to bypass the NTC after the start-up phase. The NTC bypass signal is provided from the MCU board through the J2 connector. -
