Abstract

A high-frequency link parallel resonant DC/DC power converter (PRC) operating in the lagging power factor mode with the resonating capacitor on the secondary side of the high-frequency (HF) transformer is analyzed for operation in the discontinuous capacitor voltage mode (DCVM) using a 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 of obtaining the optimum operating point under certain constraints for DCVM operation is developed and is used to develop a simple design procedure. Experimental results obtained with a MOSFET-based 1 kW PRC are presented to support the theory
