Modelling & Simulation Of Pv System With Fuzzy Mppt Based Converter

In order to cope with increased demand of energy, an efficient photovoltaic (PV) power system is to be developed which extract the maximum power from the solar model by using Maximum Power Point Tracker (MPPT). This research is focused on the implementation of Fuzzy Logic based MPPT which is compared with conventional P&O MPPT. In first stage, PV Module with Boost Converter with Fuzzy Logic based MPPT and P&O MPPT are simulated in MATLAB/Simulink. From the simulation it is founded that FMPPT can track the Maximum Power Point (MPP) with more precisely and firstly. In second stage Quadratic Boost Converter (QBC) & Boost converter with fuzzy logic based MPPT controller (FMPPT) in different solar irradiation is simulated in MATLAB/Simulink. From simulation it is observed that QBC has high voltage conversion ratio & less oscillation in transient state compared to Boost converter.
