JEE_V1_N1_A1 J. Devishree J. Anbalagan Journal on Electrical Engineering 2230 – 7176 1 1 1 4 PV module, duty cycle, irradiation, fuzzy controller, power conditioner This paper presents a Fuzzy based Maximum Power Point Tracker for Photovoltaic Applications. The proposed system contains an accurate PV module, PWM block, Fuzzy controller block and a power conditioner block. Fuzzy input parameters are Temperature in °C, Irradiation Level and Wind velocity are used to generate the optimal MPPT converter duty cycle, such that solar panel maximum power is generated under different operating conditions. The converter taken for our study is BUCK converters. For the operation planning of power systems, the prediction of power tracking is inevitable for photovoltaic systems. The simulation of the proposed system is done using the MATLAB/SIMULINK. This method gives highly accurate prediction compared with the conventional methods.
