| Abstract: | A novel zero-current and zero-voltage-switching (ZCZVS) PWM Boost full-bridge converter is proposed. The leading switches realize zero-cunent-switching(ZCS) under wide load range using the energy of the output capacitor. The lagging switches realize zero-voltage-switching(ZVS) under any load. Compared with ZCS PWM Boost full-bridge converter, the proposed converter has no current duty loss. The operation principle is analyzed in details, the parameters design is also analyzed. A 480W prototype is built to verify the effectiveness of the proposed converter. The experimental results are also vevealed in this paper. |
