Performance comparison of DC-DC Converters for Photovoltaic System

Abstract

The maximum power point tracking techniques are used to fully exploit the power output of the photovoltaic panel. This power always varies with the Photovoltaic solar irradiation and the atmospheric temperature. However, with the progress of power electronic equipment, solar panels may now be operated at their maximum power point, increasing total Photovoltaic system efficiency. Simple and Quadratic boost converters are simulated and the results are compared in this study. Then, the MPPT technique based on Incremental Conductance is proposed to improve the efficiency of the Photovoltaic system. For dynamic solar irradiance and temperature, the suggested technique's performance is simulated using MATLAB/Simulink. The analysis is based on two systems that use different DC-DC converters.
