Implementation of Fuzzy Logic MPPT in high-efficiency Double Boost DC-DC Converter Dedicated to Photovoltaic Sources

Abstract

The purpose of this paper is to develop and optimize the architecture of double Boost DC-DC converter dedicated to photovoltaic (PV) sources. The proposed system has consolidated the relation between different ranges of PV panels and DC loads. A very significant contribution proposes an innovative conversion structure aimed to achieve high efficiency, easy control, high reliability and low cost design. Since a control method of the best performance under any condition is always required, a fuzzy logic method has been chosen for this study to optimize energy transmission from the PV panel to the DC load. The experimental results confirm the reliability of this contribution, with an efficiency of 98,20%.
