Abstract

In this paper a detailed description of fuzzy logic based MPPT (Maximum Power Point Tracker) scheme for the SEPIC converter is presented for tracking the maximum power point in the PV array. Due to the fact that the output of the solar panel is not linear in nature, it has a point of maximum power which changes due to the variation in irradiance and temperature. Thus, MPPT scheme provides an opportunity for a solar panel to operate continuously at peak power point. In this work, the authors have presented the co-ordinated sequences of P&O (Perturb and Observe) and fuzzy logic control are provided to form a single algorithm for MPPT of PV DC-DC SEPIC converter for PV inverter applications. For the SEPIC converter, the fuzzy logic MPPT scheme shows a high accuracy in the current waveform and provides a constant voltage waveform and is also utilized to get the accurate sine wave output of the inverter used in the PV system. Total Harmonic Distortion is also computed for the basis of representing harmonics in the sine wave output of the inverter used in the PV system.
