Abstract

This paper introduces a new flyback-current-fed push-pull DC-DC power converter whose significant advantages in comparison with conventional designs are: reduction in the number of output diodes; and unified output characteristics to represent both the buck and the boost operation modes in the continuous conduction mode. Theoretical analysis, design methodology and experimental results taken from a 600 W, 25 kHz laboratory prototype are presented in this paper. The circuit introduced is suitable for switching mode power supply design as well as power factor correction applications
