Abstract : Insolation, temperature and array voltage largely affect the electric power received from the solar arrays and battery voltage, state of charge (SOC) and charging current affects the battery operation and its lifetime. Therefore it is needful to control the operating points by looking into both the battery parameters and the maximum power operating points from the solar array. The objective of this paper is to introduce additional control along with the maximum power point tracking (MPPT) control so as the power drawn from the solar panel can be adapted in a way to charge the battery as per the standard charging mechanism. The controller thus developed can be applied to the power processing units that are provided in appliances connected directly to the PV system. The simulation results of the buck converter with the proposed control strategy are successfully brought about by using MATLAB/Simulink.
