"This paper presents a maximum power point tracking (MPPT) control that makes use of fuzzy logic for switching a single-ended primary-inductor (SEPIC) converter for harvesting power from a photovoltaic (PV) system. The proposed FLC MPPT is presented at varying irradiances of 1000, 900, 700 and 500 W/m2 and varying temperatures of 30, 25, 20 and 18oC respectively. The SEPIC converter has a voltage output of 58.70 V for 1000 W/m2 at 18oC and the PV panel has power output at 407.7 W over 1000 W/m2 and 18oC.
The fuzzy controller for the SEPIC MPPT scheme shows good current transition and keeps the voltage constant within the acceptable limits, in variable temperatures and irradiances.
