A novel prototype of a soft-switching PWM DC-DC converter is presented in this paper. This converter consists of a half-bridge circuit assisted with an active edge resonant snubber for Zero Current Soft-switching (ZCS) commutation, and a current doubles rectifier linked with a high-frequency transformer. With the ZCS scheme and the circuit topology proposed here, the soft switching operation can be achieved for the wide range of output power under a constant switching frequency. The converter operation and characteristics are demonstrated with simulation results, and its feasibility is verified with experimental results using its 1.2kW-35kHz prototype.
