Abstract

This paper presents a novel quasi-resonant DC-DC converter using phase-shift modulation (PSM) in the secondary side of a high-frequency transformer. The proposed DC-DC converter can easily achieve soft-switching operation under the low commutating current and no freewheeling current. As a result, the conduction losses caused by their currents is substantially reduced compared with the conventional soft-switching DC-DC converters. The operation principle and analysis are illustrated and discussed by means of simulation and experimental results
