摘要
提出一种新型的零电压、零电流全桥相移脉宽调制控制开关电源．通过采用隔直电容和饱和电抗器的方法，使电源超前臂处于零电压开关状态，滞后臂处于零电流开关状态，克服了常规相移脉宽调制控制开关电源滞后桥臂零电压开关范围窄的缺点．文中给出该电源工作原理设计特点及实验结果．
This paper propose a novel zerovoltageswitching(ZVS) and zerocurrentswitching(ZCS) full bridge phase shift PWM switchingpower.By using a DC blocking capacitor and adding a saturable isductor,the leadingleg of the power was operated with ZVS,the laggingleg was operated with ZCS.The power overcomes the limitation of the narrow zerovoltage ranges of the lagging leg of the conventional phase shift control inverter.The principle of the power and the experimental result are also presented.
