- Photovoltaic electricity generators directly converts solar radiation in to electrical energy and having a lots of various significant advantages such as being silent and inexhaustible, no rotationary parts available, pollute free and size independent and higher electrical conversion efficiency. By Solar photovoltaic devices increasing various anti-pollution apparatus and penetration can be operated by solar PV power; such as, water filtration by electrochemical processing or controlling desert expansion by PV water pumping process with tree implantation. However, the power induced in output by photovoltaic array is influenced by the solar radiation intensity and temperature of this solar panel. Therefore, to improve the efficiency of the proposed renewable energy system, it’s necessary to tracking the maximum power point (MPP) of the input source. In this, Perturb & Observe maximum power point tracking algorithm is used to maximize energy conversion efficiency. In this project, The control and design issues of proposed associated system with the development of three phase grid connected photovoltaic array system inverter are describe in this project. This proposed system consists of a switching mode of DC-DC boost converter and an inverter. The switching techniques of proposed system, inverter pulse control by fuzzy logic controller with grid synchronization condition. The performances of the proposed inverter are simulated under grid-connected scenario using MATLAB. Simulation result of using fuzzy logic controller shows the minimize voltage THD level.
