Methods of Fast Analysis of DC-DC Converters-A Review

The paper discusses the methods of fast analysis of DC-DC converters dedicated to computer programmes. Literature methods of such an analysis are presented, which enable determination of the characteristics of the considered converters in the steady state and in the transient states. The simplifications adopted at the stage of developing these methods are discussed, and their influence on the accuracy of computations is indicated. Particular attention is paid to the methods of fast analysis of DC-DC converters, taking into account thermal phenomena in semiconductor devices. The sample results of computations of the DC-DC boost type converter obtained with the use of the selected methods are presented. The scope of application of particular computation methods and their duration times are discussed. Computations were performed with the use of SPICE and PLECS.
