Modeling and simulation of power electronic converters for power supplies

This paper is an update on four earlier papers that were published on the subject of modeling and simulation of power electronic converters. This paper gives an update on the micro and macro-modeling of power semiconductor devices and reviews the new simulation tools and user-friendly environment that are available for the simulation of power electronic converters with special emphasis on the analysis and design of power electronic converters that are used for power supplies. The paper discusses the subject of efficient computation of steady state and the use of symbolic math analysis for the generation of design curves. An example of a novel DC power supply with low AC current distortion is chosen to illustrate the application of the symbolic math analysis. Finally the paper suggests the addition of a benchmark 12-pulse converter scheme that is generally used for high power DC supply
