Abstract :
This paper presents 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 active voltage clamping. Theory and experimental results taken from a 600 W, 25 kHz laboratory prototype are presented
