Abstract

A high-frequency link parallel resonant DC-DC converter (PRC) operating in the lagging power factor mode with the resonating capacitor on the secondary side of the high-frequency transformer is analyzed for the operation in the discontinuous capacitor voltage mode (DCVM) using the state-space approach. Converter equations are solved for operation under steady-state condition. Based on the analysis, design curves are obtained for DCVM operation. A method for obtaining the optimum operating point under certain constraints for DCVM operation is developed and is used to present a simple design procedure. Experimental results obtained with a MOSFET-based 1 kW PRC is presented to support the theory
