Development Analysis and Performance Test of High Power IGBT Technology

Abstract

This paper analyzes the technical development of high-power IGBT and points out the structural improvement and performance improvement of the latest generation Trenchstop IGBT. An experimental circuit is designed to test the dynamic and static performance of NPT and Trenchstop IGBT which are widely used at present. The results show that Trenchstop devices have the advantages of lower on-voltage and lower off-loss etc.
