Abstract

The analysis and experimental results of a novel current-driven full-bridge zero voltage switching (CDFBZVS) DC/DC resonant power converter topology are presented. The present converter topology has a second-order tank circuit that consists of a parallel combination of a capacitor and an inductor. The converter exhibits zero voltage switching for a wide range of load conditions (from full load to open circuit). Due to the capacitive output filter, the voltage stresses in the tank circuit and the transistor switches are clamped to the output voltage. The converter is analyzed by means of a state-plane diagram from which the operational characteristics are obtained. To verify the analytical work, results from the experimental prototype are provided
