| Abstract: | The soft switching technique of symmetric full-bridge converter including the bridge arm UL,UR soft switching for the realizatiom and the lower bridge arm of LL,LR soft switching method, are analyzed. The secandary clamp to realize the peak voltage rejection in secondary rectifying bridge is introduced. The arehicle-mounted Charger of motor Vehincle using this techenology is introduced,and the test resule is given. |
