Comparative Analysis of Resonant Converters

Abstract

This paper presents the comparison among the different resonant converters especially in the Analysis of Total Harmonic Distortion (THD). The THD of output current from the inverter circuit (or) resonant current of different resonant converters such as series LC, LLC and LCC is determined. The resonant converters are to be operated above the resonant frequency to obtain the Zero Voltage Switching (ZVS) to achieve the lesser switching losses. The simulation of various resonant converters is performed in the MATLAB/Simulink software.
