语言:

中文摘要

本文研究了10-kV 10-A 4H-SiC MOSFET在6-kV直流母线电压下的短路退化行为。旨在分析器件在寿命周期内承受多次短路脉冲时的瞬态特性变化,为电力电子变换器的设计及故障保护策略提供理论依据。

English Abstract

The short-circuit behavior of power devices is highly relevant for converter design and fault protection. In this paper, the degradation during short circuit of a 10-kV 10-A 4H-SiC MOSFET is investigated at 6 kV dc-link voltage. The study aims to present the behavior of the device during short-circuit transients as it sustains increasing short-circuit pulses during its lifetime. As the short-circu...
