Abstract :
This paper deals with a new converter capable of operating in high frequency, featuring high efficiency and improved circuit EMI characteristics. The main characteristic of the circuit is to work with nonpulsating input and output currents. Besides, it presents zero-voltage switching (ZVS) and low voltage stress. Theory and experimental results taken from a 600 W, 25 kHz laboratory prototype are presented
