语言:

中文摘要

随着半导体技术进步,电力电子变换器功率密度显著提升,但高频开关带来的共模传导发射问题日益突出。本文针对Boost变换器,深入研究了滤波电感拓扑对共模噪声的影响,为优化变换器电磁兼容性(EMC)设计提供了理论依据与建模方法。

English Abstract

Recent developments in semiconductor technology and power packaging have enabled converter implementations with increased efficiency and power-density. However, the increased switching performance that makes these gains possible is also in part responsible for elevating conducted emissions signatures. A vast body of literature is dedicated to the modeling and mitigation of conducted emissions, and...
