Abstract
In this paper, a modified P&O technique that uses fuzzy logic to control the amount of perturbation depending on operating point of PV solar cell is proposed. Fuzzy logic is used to achieve smooth adaptations in duty cycles as well as to control the rate of adaptation. Proposed method helps reducing steady state oscillations and increasing convergence speed. SEPIC (Single Ended Primary Inductor Converter) is employed to realize appropriate output from proposed MPPT control. The limitation of SEPIC to track dynamic variations is overcome by fast operation of control algorithm. The system is simulated and tested in MATLAB/Simulink.
