中文摘要
采用宽禁带(WBG)半导体设计的现代功率变换器,因其高边沿速率和高频开关特性,会产生显著的传导电磁干扰(EMI)。本文提供了一种推导共模等效模型的综合方法,有助于分析这种增强的EMI特征。
English Abstract
Modern power converters designed with wide band-gap (WBG) semiconductors are known to generate substantial conducted electromagnetic interference (EMI) as a side effect of high-edge-rate and high-frequency switching. This article provides a consolidated treatment of an approach to the derivation of common-mode equivalent models that are useful for analyzing this increased EMI signature. Also inclu...
