【摘要】 对移相控制PWM变换器进行小信号分析的一种基本方法就是所谓的状态空间平均法[1]。但是该方法过程繁琐。本文提出移相控制PWM变换器本质上是由Buck变换器演变而来的概念,从而可以利用Buck变换器小信号模型建立移相控制PWM变换器的小信号模型。更多还原

【Abstract】 The traditional way of performing the small-s ig nal analysis of the PS-FB ZVS-PWM converter would be to use state-space avera ging,but it is a tedious work.A new important concept is put forward, that is, the PS-FB ZVS-PWM converter is a buck-derived topology. That implies the sma ll-signal model of the PS-FB ZVS-PWM converter would be easily set up from the counterpart of the Buck converter.更多还原
