Abstract
This paper propose an improved full bridge DC-DC converter, which can achieve ZVS with wide input voltage range and load range. By adding two clamp diodes in the primary side of the transformer, the voltage ringing across rectifier diodes is reduced. Therefore Schottky diodes can be employed and high efficiency is achieved. A 1.2 kW/105 kHz experimental circuit was made with an efficiency higher than 95%.
