Analysis, simulation and design of series resonant converter for high voltage applications

Abstract

Series resonant converters find application in high voltage power supplies where the large transformer parasitics have to be accounted for. This paper deals with the analysis, simulation and design of the phase modulated series resonant converter. Steady state analysis for the above resonant frequency operation is presented. Two modifications, one for extending the zero voltage switching range and the other providing inherent short circuit protection are also introduced. Experimental results on a laboratory model are shown to verify the design procedure.
