JEE_V2_N4_RP3 S. Padmanabhan Y. Sukhi Y. Jeyashree Journal on Electrical Engineering 2230 – 7176 2 4 16 26 zero voltage switching, zero current switching, DC-DC Converter, Resonant converter, Soft switching In this paper a pulse width modulated series parallel resonant converter is presented. The performance of the converter for constant output voltage with variable input and variable load is analyzed. This configuration is well suited for many applications where output is fairly constant but the input is required to vary widely without serious switching losses and with significant reduction in ripple content. Experimental results obtained from a laboratory prototype are presented. April - June 2009 Copyright © 2009 i-manager publications.
