Fuzzy Logic Controller based Maximum Power Point Tracking Using DC/DC Boost Converter for PV System

Solar energy efficiency is mainly related to changes in weather such as temperature and irradiation conditions, in light of these changes and non-linearity of the I-V characteristic, techniques and algorithms are relied on to increase efficiency and rapid response in all conditions by tracking the maximum power point of the solar energy system. This paper proposes an MPPT based on a fuzzy logic controller (FLC) using a boost converter for a photovoltaic system under variable conditions and Compares the results using the P&O method. The study was carried out by MATLAB/Simulink. Simulation results demonstrate that of FLC-based MPPT delicate tracking of MPP at different climatic conditions.
