Abstract: The aim of this work is to analyse and study the difference between LCC and LLC DC-DC resonant converter for high voltage applications, the two types of resonant converter are discussed, tested using MATLAB and the performance are compared. Simulation studies are carried out using MATLAB / SIMULINK model. The output voltage, output current and voltage gain of both type of comarators are calculated and studied. After the analysis of LCC and LLC resonant converters, it is found that the LLC converter can give more gain characteristics compared to LCC converter and also with more output voltage. Thus the characteristics of two resonant converters are studied and compared.
