Abstract
In this paper, a system is proposed for maintaining alternating current with the desired characteristics of a closed loop configuration photovoltaic (PV) system. The generated output current from the PV system is highly dependent on the temperature and intensity of the solar radiation. The proposed system overcomes these critical issues by using a closed loop current control, resulting in an alternating current (AC) output of constant frequency and amplitude. The proposed system consists of a photovoltaic cell array, current controlled inverter, closed loop current control and LC filter. The closed loop strategy helps to get nearly ideal AC output. Low pass filtering is employed to further enhance the AC response. The system is developed and verified in MATLAB-Simulink.
