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 ...
