A Novel Fuzzy Based Modular Seven Level Cascaded Inverter Using P and O MPPT for the Application in Single Or Three Phase Grid Connected Systems

Abstract

This project illustrates that a novel Fuzzy based modular Seven Level converter applied for grid connected systems used to rectify the distorted current waveforms in a single phase or a three-phase systems by P and O based technique. The Perturb and Observe MPPT (maximum power point tracking) is a technique used in solid state converters to extract maximum energy from the photovoltaic (PV) systems. Also increases the system efficiency and flexibility of PV systems which realizes the utilization of maximum solar energy and has a independent control of each bridge and each DC-link. The major advantage of this type is to reduce the distorted current waves a fuzzy based modulation is presented for a 185W solar system. Some results such as current, voltage and output power for each various combination have been recorded. The simulation has been accomplished in software of MATLAB Math works.
