MPPT OF PV CELL USING P & O AND FUZZY LOGIC CONTROLLER ALGORITHM FOR BUCK-BOOST DC-DC CONVERTER

Abstract

 Non-conventional power generation is one of the fastest growing sectors. Globally, all countries are busy developing and implementing nonconventional power to bridge the electricity demand and power supply gap. The sun is the ultimate source of limitless solar energy in the form of light and heat. Light of the sun is directly converted into electrical energy without any inter mediate step. Solar photovoltaic (PV) power is leading ahead of the other sources. In a solar power generation system, the PV cell plays a major role. Rural coastal communities in developing countries along the equator lack electricity, due to the expenses involved with connecting them to the power grid. An affordable local solution, such as onsite micro power generation, would benefit the local communities and fulfill their basic lighting and ventilation needs. Equatorial coastal areas have constant high incident solar radiation. Therefore, these regions would be ideal to implement a solar power generation unit. This project involves the development of a solar panel to generate direct current (DC) power that will be used to charge a battery. And this DC voltage from battery is converted into AC using inverter. This system will provide the basic electricity requirements for the house.
