PV System Based Novel Power Management for AC Grid Using CUK and Isolated Bi-Directional DC-DC Converter

ABSTRACT: Nowadays electricity has become the inevitability of humans to carry on their works. As we know we are running out of resources. In order to accomplish the requirement, we are making enhancements in the prevailing technologies. When a solar PV Array (PVA) is used for electricity generation using the sun's energy. This paper deals with optimal management of power in residential areas by utilizing the energy generated by the PVA when it is operational, so that the energy which is consumed under normal conditions from the grid can be saved by using a nonrenewable source of energy. The main idea is to save electricity from the grid to the maximum by generating electricity using PVA that generates electricity using solar energy. But by using PVA to generate electricity leakage occurs. This leakage is minimized by using Bi-Directional Converters in the circuit which boosts the voltage generated by PVA to the required level of the voltage. This paper is proposed to design a Bi-Directional Converters for photovoltaic Arrays (PVA) system using PICmicrocontroller.
