In this paper, the authors deal with the analysis and design of LLC resonant converter suited for photovoltaic applications. The proposed converter maximizes battery life without penalizing the volume of the charger. Theoretical values of turns ratio, resonant inductor, resonant capacitor, magnetizing inductor are calculated using design equations. Switching losses and voltage ripple are calculated. Also performance parameters such as efficiency and voltage gain are calculated and compared with LCC Resonant converters. Simulation studies are carried out using Matlab/Simulink. A prototype of the proposed LLC resonant converter is built to validate the simulation results.
