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 converters. soft-switching obtained by using both the leading switches and the lagging switches. softswitching PWM 3L and 5L converters can be classified into two kinds: zero-voltage-switching (ZVS) and zero-voltage and zerocurrent-switching (ZVZCS), A three level & five level ZVZCS converters are presented, its operation principle, and the simulation results obtained by using PSPICE are included also.
