Abstract :
This paper presents some of the issues involved in applying frequency-selective averaging to modeling the dynamic behavior of PWM DC-DC converters. We use the boost converter as an example to show the details involved in deriving some novel averaged models and use simplifications to highlight the accuracy of the models even when traditional small-ripple conditions are not satisfied.
