Abstract :
Conventional averaged models of switching power converters are useful for control loop design, but are inadequate for the main circuit design because of their inability to predict waveform details. A systematic method for recovering ripple components from the averaged model is presented in this paper. The method has been implemented in a symbolic analysis program package which allows automatic ripple analysis in conjunction with averaged modeling. Applications of the method and the package are demonstrated using a PWM DC/DC power converter and a line-frequency AC/DC power converter
