Modeling of power electronic converters

Abstract

In Chapters 3 and 4 the components in power electronics converters, such as the switches, the sources, and the transformers, have been finally modeled by combining resistors, inductors, capacitors, power sources, and ideal transformers. Therefore finding how to model such a network constituted by those circuit elements will lead to the solution of modeling power electronic converters. This chapter introduces the theorems, principles, and approaches used in modeling power electronic converters. Kirchhoff’s laws are introduced first, followed by the numerical discretization methods of continuous states in the circuit. Two mainstream modeling approaches used in the power electronics real-time simulation ...
