Simulation of Power Electronic Systems

Difficulties and Keys

Abstract

Recently, with the advent of computer technologies, a plenty of simulators for power electronic systems have been developed and computer simulations have been more powerful and useful tools for analysis and design of power electronic systems. However, there often arise several problems and difficulties in simulating power electronic systems due to the distinguishing characteristics of power electronic systems such as nonlinear switching behaviors, characteristic hybrid features, stiffness and so on. In this paper, after briefly describing general simulation methods, we pick up some of those problems and explain why and how those problems arise and how to resolve them.
