Abstract

This paper reveals three-phase high frequency isolated, symmetrically controlled, LLC DC-DC resonant converter with inductive output filter and its operation with waveform and equivalent circuits. Mathematical modeling of LLC resonant tank network is presented and its design curves are plotted against variation of normalized frequency for various Q-factor. Based on the design curves, simulink model of converter is developed using MATLAB SIM Power System toolbox and simulation is carried out to investigate its performances for low voltage high current applications and obtained simulation results.
