Abstract
This paper proposes a dynamic small signal model of the constant-frequency pulse width modulator of switching converters. The existing model is represented as a simple gain block Fm, which is relatively short in both accuracy and physical meanings. Employing the methods of probability, this dynamic model provides a more accurate prediction of the system behavior in the sense of statistics, compared to its previous counterpart
