A New Asymmetrical Current-fed Converter with Voltage Lifting
Advances in Electrical and Computer Engineering, 2011 This paper presents a new zero voltage switching current-fed DC-DC converter with high voltage gain. In this converter all switches (main and auxiliary) turn on under zero voltage switching and turn off under almost zero voltage switching due to snubber
