Abstract :
This paper proposes a zero-voltage-switching PWM three-level converter with current-doubler-rectifier, which achieves ZVS for all the switches under wide load range and in a wide line range. The rectifier diodes commutate naturally, therefore no oscillation occurs. The experimental results are presented to verify the operation principle of the proposed converter
