摘要
对偶原理是分析电力电子电路拓扑结构的有力工具。本文根据图论中图的对偶概念,对电力电子电路进行了对偶性分析,介绍了电力电子电路对偶变换的方法。由于对偶原理只适用于平面电路,本文还通过新的概念定义以及适当的变换方法将对偶原理的应用扩展到了非线性电力电子器件与非平面电路中。文中最后举例说明了对偶原理在电力电子拓扑结构中的重要作用。
Duality principle is a powerful tool for the analysis of topological structure of power electronic circuits.The duality of power electronic circuits has been analyzed using the concept of duality in graph theory and the methods of dual transform in power electronic circuits are also introduced in this paper.Traditionally,duality principle is limited to linear circuits.In this paper,the application of duality principle has been extended to non-linear power electronic devices and non-planar circuits using new...
