Description

The goal of the STEVAL-IHM028V1 demonstration board is to present a universal, fully tested, and populated design consisting of a 3-phase inverter bridge based on the 600 V, 17 A intelligent power module STGIPS20K60. The IPM itself consists of short-circuit rugged IGBTs with negative temperature co-efficiency. It also contains a wide range of auxiliary functions like undervoltage lockout and smart shutdown.

Thanks to these advanced characteristics, the system has been specifically designed to achieve an accurate and fast conditioning of the current feedback, therefore matching the typical requirements for a field oriented control (FOC).

This demonstration board can be used for evaluating a wide range of applications such as
