摘要

This paper presents the MPPT (Maximum power point tracking) operation of PV (Photovoltaic) system based on a SEPIC (Single Ended Primary Inverter Converter) converter using fuzzy logic controller. MPPT method such as Incremental conductance base on FLC (Fuzzy Logic Controller) is used to extract maximum output power of the PV system. PV energy is the most essential energy resources since it is pollution free, clean and endless. The FLC proposed scheme is interface with the MPPT to generate the PWM (Pulse Width Modulation) for the SEPIC controller for maximum power point tracking operation.FLChas used Mamdani's method for convergent and divergent of membership function. FLC is used for more efficient performance under the variation in different atmosphere. The fuzzy logic controller with SEPIC for MPPT scheme extract the maximum power point tracking without any change in the voltage at the inverter at different load condition. The behavior of the converter and controller tested in simulation at different operating conditions. Proposed scheme is used for accurately tracking maximum point and also send the smooth, error free signal to the inverter.
