Abstract :
The application areas of traditional push-pull converters are limited because the voltage stress of switches is high (twice the input voltage). In this paper, a zero-voltage and zero-current-switching PWM push-pull three-level converter (ZVZCS PWM PP-TL converter) is proposed, in which the voltage stress of switches is the input voltage. Phase-shifted modulation strategy is employed, the leading switches realize ZVS, and the lagging switches realize ZCS. The operation principle of the proposed converter is analyzed and verified by experimental results. Several other ZVZCS PWM PP-TL converters are also proposed in this paper
