Abstract

In this paper, the general operation principles for the existing control type ZVT PWM dual switch forward converters which possess the same conversion ration are reviewed and their advantages and drawbacks are discussed in detail. Then the control type ZVS techniques of active-clamp and resonant reset are extended to the other dual switch forward converters by whether employing the input for resetting the transformer or not and a family of control type ZVT dual switch forward converters is derived and summarized detailedly. In the same way, the new families of control type ZVT PWM flyback and forward-flyback converters are brought forward. A new and improved control type ZVT PWM dual switch forward converter is proposed and its experimental results confirm the superior performance over the others in the same family.
控制型ZVT PWM双开关正激变换器的比较研究:分析、总结和拓扑扩展
本文综述了现有具有相同转换比的控制型ZVT PWM双开关正激变换器的一般工作原理,并详细讨论了它们的优缺点。然后将有源箝位和谐振复位的控制型ZVS技术推广到其他双开关正激变换器中,不论是否采用变压器复位输入,导出并详细总结了一类控制型ZVT双开关正激变换器。同时,提出了控制型ZVT PWM反激变换器和正激反激变换器的新系列。提出了一种新型的改进控制型ZVT PWM双开关正激变换器,实验结果表明其性能优于同类变换器。
