TLDR
In this paper, a nonlinear discrete-time dynamic model for the series resonant dc-dc converter is derived using approximations appropriate to most power converters, and compared with a laboratory converter for a large transient event.Abstract:
A simple nonlinear discrete-time dynamic model for the series resonant dc-dc converter is derived using approximations appropriate to most power converters. This model is useful for the dynamic simulation of a series resonant converter using only a desktop calculator. The model is compared with a laboratory converter for a large transient event.read more

A General Approach to Sampled-Data Modeling for Power Electronic Circuits
TL;DR: A general sampled-data representation of the dynamics of arbitrary power electronic circuits is proposed to unify existing approaches and lead, via compact and powerful notation, to disciplined modeling and straightforward derivation of small-signal models that describe perturbations about a nominal cyclic steady state.

TL;DR: In this article, the small signal response of resonant converters to small signal perturbations in the switching frequency and input voltage is determined, and it is shown that the dc-to-dc conversion ratio can be controlled by changing the ratio of switching frequency to resonant frequency.

A Normalized Model for the Half-Bridge Series Resonant Converter
R.J. King,T.A. Stuart +1 more
TL;DR: In this article, closed-form steady-state equations are derived for the half-bridge series resonant converter with a rectified (dc) load, and normalized curves for various currents and voltages are then plotted as a function of the circuit parameters.
