Fuzzy logic maximum power point tracking control for PV inverter

A fuzzy logic controlled (FLC) MPPT controller based on the perturb-and-observe (P&O) algorithm presents in the paper. It can effectively reduce power waste and attain the high rates voltage conversion by using the proposed converter with the FLC MPPT. A stand-alone PV inverter system is proposed that contains a high conversion ratio converter with the FLC and a dc/ac inverter with phase-lock loop design. The simulation and experimental results for the PV inverter with the FLC MPPT control to verify the effectiveness of the proposed method.
