Abstract

This paper proposes the maximum power tracking from the Photovoltaic system, which is interfaced with utility grid through a three phase inverter, by using a fuzzy logic controller. In this arrangement, three phase step up transformer is used to synchronize the inverter output with the grid ratings. Controller tracks and feeds maximum power to the utility grid. The linguistic variables have been selected appropriately to modulate the firing angle of the inverter for tracking the maximum power. MATLAB/SIMULINK has been used to model fuzzy logic controller. Complete model of the system has been presented in detail. Also, simulation results are presented and described.
