Experimental Analysis of New Charge Controller for Solar PV Systems

Abstract

Globally, abstraction rate of electrical energy has been increased from Renewable Energy Resource (RER). Because of, RER are ubiquitous, freely available and environmentally free. Besides, conventional fossil fuels are finite and also which are harming the environment. At present, the solar power plants are contributing more electrical energy that of others. Which is due to solar resources are available in a unique manner on all land areas as well as technically feasible. The heart of the solar PV system is charge controller which maintain the output of PV at desired level. Since it operating two modes such as buck and boost. According to the available solar irradiation it can operate. Hence, in this article proposed a new charge controller for PV system. The proposed system has a solar PV with capacity of 3W/6V, battery of 6V/4.5 AH. Moreover, the switching devices are made by MOSFET due to it offers very low switching loss. From experimental validation, the developed new charge controller working satisfactory.
