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

Zero-Voltage and Zero-Current Switching Converters
International Journal of Computer Applications, 2010 This paper deals with the simulation of a PWM three-level (3L) & five level (5L) converters. The modulation strategies can be classified into two kinds according to the turn-off sequence of the two switches of the pair of switches. The concept of the leading switches and the lagging switches is introduced to realize softswitching for PWM 3L and 5L ...
