中文摘要：
提出了一种新型零电压转换(ZVT)正-反激组合式PWM变换器,该变换器兼具正-反激变换器的优点,采用了软开关技术,并且只用一个变压器实现了单路输出,从而可以大大降低变压器的损耗,实现主开关管的零电压开通和零电压关断。给出了实现电路,并对其工作过程进行了详尽的分析,提出了变压器的设计方法,讨论了ZVT的实现条件,设计了关键参数。并通过电路仿真软件ORCAD进行了仿真研究,其结果表明了理论分析的正确性。
英文摘要：
A novel ZVT forward-flyback converter combining advantages of forward converter and flyback converter is presented.Soft-switching technology is used and the voltage output can be achieved by only one transformer instead of two like in other ordinary soft-switching converter,so that the switching losses are reduced greatly,and the main switch is turned on and off at zero voltage.The realization circuit is given and work process is analyzed in details,and the design method of transformer is presented.Conditio...
