Abstract :
By the analysis of the ZVZCS phase shifted full bridge PWM DC-DC converter with secondary auxiliary circuit, the parameters of the circuit are optimized to improve the performance of the converter. The conditions to achieve ZVS (leading-leg) and ZCS (lagging leg) are discussed. The loss of the ZVZCS. converter is decreased under the novel working mode. The principle of operation features and design considerations are verified on a 1.5 kW IGBT based prototype
