High power transistor modules with intelligent functions

Abstract

This paper presents high power transistor modules with intelligent functions such as self-protection and self-diagnosis. The current capacity of the modules rangesfrom 30A to 150A. Two key technologies for high power intelligent modules with compact size are reported. One is the development of power transistor chips (high hpE transistors and low loss IGBTs) and the other is the development of new module packages. This is the first demonstration of intelligent power modules more than 50A current capacity.
