A Study on Efficiency Improvement of F-B Converter with Phase-shifted control method

This paper is concerned on developing DC-DC converter. In contrast to resonant converter, this converter requires no external resonant elements and operates with constant switching frequency. In conventional PWM converter, two MOSFET switches of the converter are simultaneously turned on and turned off. In presented converter, to achieve Zero Voltage Switching, the two legs of the bridge are operated DC-DC converter is phase shifted. Phase shifted Full Bridge ZVS PWM Converter have an effect on the power system. Operation principle and features are illustrated by the experiment results from 50W, 250kHz with MOSFET switch.
