摘要 研究了一种新型的高频DC/DC开关功率变换器,采用单电压环移相PWM控制,在比较低的变压器匝比条件与较大的负载范围内实现了开关器件的零电压软开关(ZVS)。最后给出了实验结果和几个主要波形,并做出了详细的说明。 A high frequency DC/DC power converter is presented. The control strategy of this converter is voltage-mode phase-shift PWM control. And it achieves zero voltage switching（ZVS） at a wide variety of loads and small turns ratio. At last, the experiment results and waveforms are presented and expounded in detail.
