| 摘 要： | 在分析ZVZCS-PWM软开关工作原理的基础上,提出了一种利用耦合输出电感的新型次级箝位ZVZCS-PWM变换器.该变换器采用了不带损耗元件和有源开关的简单辅助电路,减小了次级整流二极管的电压应力,且轻载时箝位电容的充、放电电流能根据负载情况自动调整.最后,成功得出了变换器的设计参数并给出了实验结果.

| Abstract: | This paper proposes a novel ZVZCS-PWM converter using a coupled output inductor on the basis of analyzing the principle of ZVZCS-PWM soft switching.This converter uses a simple auxiliary circuit without the active switch and lossy components so that the voltage stress of secondary rectifier diode is reduced and the current to charge or discharge clamping capacitance is self-adjusted in accordance with the load.Finally,the design parameters derived from the analysis and the experimental results are given. |
