反激式变换器DCM与CCM模式的分析与比较

The Analysis and Comparison between Discontinuous Conduction Mode and Continuous Conduction Mode of Flyback Converter

反激式变换器有两种工作模式,一种是不连续导通工作模式(DCM),另一种是连续导通工作模式(CCM)。文中在分析其工作原理的基础上,通过推导计算两种模式下主要参数的大小,从不同的方面来分析二者的优缺点,进而得出相关的结论。

There are two modes in flyback converter,one is the discontinuous Conduction conduction mode（DCM）,and the other is the continuous conduction mode（CCM）.Before analyzing the basis of flyback converter and calculating the main parameter of two modes,this paper analyzes the advantages and disadvantages of DCM and CCM from different aspects,some interrelated conclusions are given at last.
