In this article the analysis of electromagnetic processes in electrical circuits with semiconductor switches has been performed. A mathematical model for analysis of electromagnetic processes in semiconductor converter with pulse-width regulation of output voltage has been developed. Time diagrams reflecting electromagnetic processes in electrical circuits are presented.

Today one of the most powerful tools for calculations, analysis and optimization of semiconductor converters (SCC) of electrical energy and devices of power and information electronics are modern software packages of personal computers (PC). The practical use of this software is especially relevant and justified now, when the capacity and software of modern PCs in the age of enchanced informativity have been developed to such an extent that users only need to focus their efforts on solving scientific and technical problems in a certain fields of their specialization. In this work the package MATHCAD has been applied.
