Abstract :
This paper introduces a new flyback-current-fed push-pull DC-DC converter whose significant advantages in comparison with the conventional one are a 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 and power factor correction applications as well
