| Abstract: | This paper proposes a Zero-Voltage-Switching PWM Hybrid Full-Bridge Three-Level (ZVS PWM H-FB TL) converter with current-doubler-rectifier (CDR), which achieves ZVS for all the switches in the entire line and load range. The rectifier diodes commutate naturally, therefore no voltage spike and oscillation occurs. The converter is helpful to reduce filter inductance current ripple and output current ripple. It is also suited for wide input voltage applications. The experimental results are presented to verify the operation principle of the proposed converter. |
