Complementarity Model for Steady-State Analysis of Resonant LLC Power Converters

In recent years, the complementarity formalism has been shown to be an interesting framework for the mathematical representation of a large class of power converters. In this brief, the complementarity model of a resonant LLC power converter is presented. The model usefulness is demonstrated for the identification of the circuit parameters and for the numerical analysis of the stationary behavior. The comparison between experimental measurements and numerical results shows the efficacy of the proposed approach.
