Abstract
This paper proposes a high efficiency hybrid full bridge converter with phase shift control. By adding a small auxiliary transformer, the transfer gain of the converter is higher than of conventional phase shift control full bridge (PSFB). With an improved rectifier structure the reverse recovery of the rectifier diode is reduced, and the filter inductor requirement is reduced as well. A prototype (500 W/125 kHz) is made to verify the theoretical analysis.
