摘要

This paper presents a new prototype of phase-shifted transformer parasitic components-assisted ZVS-PWM DC-DC converter with a choke input type DC smoothing filter which incorporates ZCS active power switches in series with each rectifier diode in the high-frequency transformer secondary-side. This efficient DC-DC converter with a wide ZVS operation ranges which is suitable for high power applications can achieve soft-switching operation under a condition of no circulating current. Its operating principle and unique features are described. The steady-state operating characteristics of the proposed DC-DC converter topology are illustrated and discussed on the basis of the simulation and some experimental results of 2 kW-40 kHz breadboard set up.
