Abstract

The new generation of Integrated Power Module (IPM) is introduced in this paper for home appliance applications. The combined benefits of advanced Trench IGBT technology and optimized package design have enabled us to achieve higher efficiency and improved reliability, along with minimized module and system cost. The Trench IGBT is able to deliver up to 30% loss reduction compared with NPT IGBT of same die size. Besides, the new IPM has achieved as much as 50% reduction in IGBT junction temperature ripple, thanks to the thermal mass provided by heat spreader.
