Abstract :
This paper focuses on the ZVS operation and design considerations for a ZVS DC-DC full bridge converter. With the proposed circuit diagram the efficiency can be improved comparing with a conventional phase shift full bridge (PSFB), and the voltage ringing across the rectifier diodes can be reduced significantly by clamp circuits. A 1.2 kW (50 V/24 A) prototype with a efficiency of 95% is made to verify the theoretical analysis.
