TLDR
Novel small-signal averaged models for dc–dc converter operating at variable switching frequency are derived by separately considering the on-time and the off-time of the switching period.Abstract:
In this paper, novel small-signal averaged models for dc–dc converter operating at variable switching frequency are derived. This is achieved by separately considering the on-time and the off-time of the switching period. The derivation is shown in detail for a synchronous buck converter. The Enhanced Small Signal (ESSA) Model is derived for the synchronous buck converter. The equivalent series inductance (ESL) is also considered in this modelling. The buck converter model is also simulated in MATLAB and the result is also presented.read more

Averaged modeling of PWM converters operating in discontinuous conduction mode
TL;DR: In this article, a duty ratio constraint that defines the diode conduction interval is identified to be the key to accurate prediction of high-frequency behavior of hard-switching pulse-width modulated (PWM) converters.
