STEVAL-IHM028V2

STM-STEVAL-IHM028V2-EVAL document describes the 2 kW 3-phase motor control evaluation board featuring the IGBT intelligent power module STGIPS20C60. The evaluation 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.

Minimum input voltage 125 VDC or 90 VAC Maximum input voltage 400 VDC or 285 VAC With applied input voltage doubler - the range from 65 VAC to 145 VAC Maximum output power for applied motor up to 2000 W Regenerative brake control feature Input inrush limitation with bypassing relay +15 V auxiliary power supply based on a buck converter with VIPer™26 Using IGBT intelligent power module STGIPS20C60 in SDIP 25L molded package Fully populated board conception with test points and safety isolated plastic cover Motor control connector for interface with STM3210B-EVAL board, STM8/128-EVAL board, and other ST motor control dedicated kits Tachometer input Hall/encoder inputs Overheating protection Active fan cooling of heatsink with automatic temperature switch Possibility to connect MB843 BLDC daughterboard for sensor-less six-step control PCB type and size: Material of PCB - FR-4 Double-sided layout Copper thickness: ~60 µm Total dimensions of evaluation board: 195 mm x 175 mm
