A novel ZVS-PWM full-bridge converter topology

In this paper, a novel ZVS-PWM full-bridge converter topology is proposed. ZVS can be achieved for the lagging-leg by using the energy stored in the leakage inductor in heavy load condition while using energy stored in both the leakage inductor and magnetizing inductor in light load condition. An 84...

Description
Summary:In this paper, a novel ZVS-PWM full-bridge converter topology is proposed. ZVS can be achieved for the lagging-leg by using the energy stored in the leakage inductor in heavy load condition while using energy stored in both the leakage inductor and magnetizing inductor in light load condition. An 840 W prototype based on the proposed topology is built up and a relatively high efficiency has achieved.
