电力电子变流器中涡流损耗的一种算法

A Algorithm for the Eddy Current Loss in the Power Electronic Converter

本文经过推导，找到了一种可用来计算电力电子变流器电路中周期非正弦电流在铁磁器件中引起涡流损耗的微分电流法，并用实例说明了它的应用，证明了它较传统的Ｆｏｕｒｉｅｒ谐波分析方法简单、方便，有实用价值。

In this paper,a differential current algorithm is putforward to calculate the eddy current loss of the ferromagneticmaterial caused by the periodic non-sinusoidal current in the power electronic converter.The examples show that how it workand the result proves it is more convinient,useful and simpler than the classic Fourier harmonic analysis.
