Analysis and design of a parallel resonant converter with secondary-side resonance

A high-frequency link-parallel resonant DC/DC converter with the resonating capacitor on the secondary side of the high-frequency transformer is analyzed using the state-space approach. Design curves are obtained, and a simple design procedure is illustrated by an example. Experimental results obtained with a MOSFET-based 1-kW converter using a high-frequency transformer with turns ratio of 1:1 is presented to support the theory.<>
