| 摘 要： | 提出一种改进型的移相全桥零电压零电流倍流整流变换器.采用变压器和隔直电容串联,滞后桥臂串联二极管,使其超前桥臂实现零电压开通,滞后桥臂实现零电流关断,与滞后桥臂串联的二极管也实现零电流关断,二次侧整流二极管也是自然关断,变换器所有的功率器件都有较大的软开关范围,文中还简单讨论了软开关范围和参数设计.最后,采用峰值电流控制,电压外环、电流内环的控制方案,研制2.5kW的软开关全桥变换器,并给出实验结果.

| Abstract: | An improved phase-shift full-bridge zero-voltage zero-current switching(ZVZCS) converter with current doubler rectifier is proposed.By using a DC-block capacitor in series with the transformer and a diode in series with the lagging-leg,zero-voltage switching for the leading-leg and zero-current switching for the lagging-leg can be achieved respectively.The diodes in series with the lagging-leg are turned off under the zero current condition,and the rectifier diodes in the secondary side were turned off natu... |
