대용량 전력변환용 초고전압 NPT IGBT 최적화 설계에 관한 연구

Abstract

This paper was proposed the theoretical research and optimal design 3,000 V IGBT for using electrical automotive, high speed train and first power conversion. To obtaining 3,000 V breakdown voltage, the design parameters was showed resistivity and drift length. And to maintain 5 V threshold voltage, we obtained p-base dose. We confirmed cell pitch for maintain optimal on state voltage drop and thermal characteristics. This 3,000 V IGBT was replaced to thyristor devices using first power conversion and high speed train, presently.
