摘　　要：反激变换器是小功率家电和手持设备中最常用的电源系统,反激变换器特殊的工作过程决定了其设计方法异于正激变换器。本文对反激变换电路进行研究,介绍了从变压器电感特性出发进行设计的方法,这种方法与等效Boost设计方法和电能守恒法相比,更明确的体现了反激变换器的电路原理。Flyback converter is the most used power system in household The different design method was decided by its special circuit characters dissertation studied the mode of Flyback circuit, introduced the design appliances and hand-in electrical equipments. with forword topology.With this regards, the method based on the transformer＇s inductor character, this method with compared to the Boost equivalent design method and energy conservation law which definitely reflect the nature of Flyback topology

关 键 词：反激变换 设计方法 电感特性
