Abstract

The need for DC-DC converters is increasing day by day. There are several types of DC-DC converters that have been introduced in the recent years. Among these the non-inverting buck- boost converters are used to step-up or step-down the input voltage based on the requirements. But these converters have high switching losses and hence its efficiency is reduced. In order to overcome these switching losses resonant converters are used. The resonant converters are more efficient than the ordinary buck-boost converters. By operating the resonant circuit above or below the resonant frequency, Zero Voltage Switching and Zero Current Switching of MOSFETs are possible. These types of switching methodologies reduce the switching losses. Thus the overall efficiency of the resonant converter is high when compared to the buck-boost converters. In this project, MATLAB simulation of closed loop control of LCLC DC-DC resonant the resonant converter is done using PI controller and their performance is analyzed.
