A new multi-functional compact IPM for low power industrial application

This paper presents a new intelligent power module (IPM) family dedicated for low power industrial inverter drive applications, especially for low cost and compact size requirements. The new IPM family integrates converter, inverter, brake and driver circuits into a compact, high reliable transfer-molded package with fine cell pitch Carrier Stored Trench-gate Bipolar Transistor (CSTBTTM) power chips, optimized internal layout and direct gate wire bond structure. As a result, the new IPM products achieved both high performance and small size. The inverter main driver circuit that utilizes the new IPM can achieve about 50% reduction on PCB size compare with those uses IGBT modules or discrete parts.
