Abstract :
A family of zero-voltage-switching (ZVS) dc-dc transformers is proposed in the paper. Utilizing the magnetizing current, all switches can realize ZVS independent of input voltage and load. A ZVS push-pull forward dc-dc transformer is used to illustrate the concept. The switches´ ZVS condition is theoretically analyzed. Simulation and experimental results verify the analysis. And the experimental results indicate that it can achieve 95% efficiency at full load
