- Abstract:
- The improved current-doubler-rectifier zero-voltage-switching PWM full-bridge converter(CDR ZVS PWM FB converter)achieves ZVS for the switches in a wide load range with the use of the energy stored in the output filter inductances, and the rectifier diodes commute naturally, therefore no oscillation and voltage spike occurs. The transformer needs no special manufacture method to limit the leakage inductance. The ZVS achievement and the design considerations for the output filter inductances and the blocking capacitor are discussed for the improved CDR ZVS PWM FB converter. A 540 W prototype converter is built in the lab to verify the operational principle and design considerations for the improved converter, the experimental results are also included.
- 针对改进型倍流整流电路零电压开关PWM全桥变换器(CDR ZVS PWM FB变换器), 讨论了超前管和滞后管各自实现ZVS的特点, 对滤波电感的电感值和阻断电容的电容值进行了优化选择, 使变换器在很宽的负载和输入电压范围内实现开关管的ZVS, 输出整流二极管实现自然换流, 没有电压尖峰, 同时对变压器的漏感没有严格要求.通过一个540 W的原理样机验证改进型变换器的工作原理和设计的正确性, 最后给出了实验结果.
