Mathematical calculation of H – bridge IGBT power convertor

In this paper mathematical modeling of the magnitudes of H bridge power converter with serial resonant load is presented. A mathematical analysis of the IGBT switches operation mode in the power converter is given. The operation of the IGBT transistors in the converter is described by a set of differential equations. The differential equations calculations that describe the work of IGBT switches are derived from the mathematical program Mathematica 7. The results in the paper are applied in practical realized the power converter
