摘要
研究一种把软开关技术和移相PWM控制技术以及双向DC DC变换器技术有机结合在一起的新型高频DC DC开关功率全桥变换器。它采用电流模式移相PWM控制,在较大的负载范围内实现了开关器件的零电压软开关(ZVS)。该电路简单高效,超前臂、滞后臂都能在很宽的范围实现软开关。介绍和分析了变换器的工作原理,最后给出了实验结果和两个主要波形,并做出了详细的说明。
A new high frequency DC- DC full-bridge power converter is presented, that the soft-switching, phase-shifted PWM and hi-directional DC- DC converter hang together. The control strategy of this converter is current-mode phase-shift PWM control, and it achieves zero voltage switching（ZVS） at a wide variety of loads. The converter is simple and efficient, and the lagging-leg as well as the leading-leg can achieve soft switch in a very broad range of loads. The operation principle of the converter is explained. At last, the experiment results and waveforms are presented and explored in detail.
