Fuzzy Logic Based MPPT Algorithm for Solar PV systems

The studies on photovoltaic systems are extensively increasing now days. The various techniques and algorithms are proposed to increase the efficiency of solar systems. In this paper, a maximum power point tracking algorithm based on fuzzy logic is presented. The designing of whole system is done in MATLAB/Simulink environment. The fuzzy logic controller is designed to give a good response to the variations in solar radiation and cell’s temperature. The controller is used to change the duty cycle of DC-DC converter which is the control parameter. The simulation results show that the proposed system effectively increase the efficiency of the system.
