The linearized dynamic model of the series resonant converter for small signals

Abstract

Processes in the power scheme double-bridge series resonant converter are considered. The equivalent circuit of the converter based on the imposition of linear active resonant contours with sources of rectangular form voltage is applied to the analysis of processes. The expressions for the discrete the control-to-output-envelope transfer functions of the active resonant contour and of the resonant converter are received. The block scheme of the converter dynamic model based on typical transfer links is offered. Recommendations for the use of the obtained expressions are offered.
