| 摘 要： | 以结合开关理论为基础，提出了一种可以建立软开关PWM变换器的系统方法。应用这种方法，许多种无源和有源软开关PWM变换器家族中所派生出的变换器，如：Buck—Boost变换器、Cuk变换器、Sepic变换器和Zeta变换器都能够通过Buck变换器和Boost变换器这两种最基本的变换器得到，不仅对变换器家族可以进行更加深入的了解，还可以揭示出软开关变换器之间的内在联系。通过对结合开关理论的具体介绍，在对有源PWM软开关变换器中的零电压转换（ZVT）PWMDC／DC变换器的派生变换器电路拓扑的建立原理和得出过程重点阐述的同时。将有源软开关PWM变换器进一步分成了Buck和Boost家族两大类，并证明了所提出的这种建立软开关PWM变换器的方法的正确性和可行性。

| Abstract: | A systematic approach to developing soft switching PWM converters based on the graft switch theoretic is presented.With the approach,several families of active soft switching PWM converters,such as buck-boost,Zeta,Cuk,and Sepic,can be generated from the two basic converters,buck and boost.Also,employing the technique can not only explore more physical insights into the converters in a family but reveal more relationships among the soft switching converters over conventional approaches.The active soft switching PWM converters are classified into buck family and boost family,in addition,the principle and the process of several families of the ZVT soft switching PWM converters in the active soft switching PWM converters were expounded respectively by recommending the graft switch theoretic,which have verified the feasibility and validity of the derived soft switching PWM converters. |
