Reverse Voltage Multilevel Inverter for Photovoltaic System with Fuzzy logic based MPPT Controller

Abstract

For high power equipments in Industry, application of multilevel inverter has become popular. So, multilevel inverter have been widely used for high-power high voltage distributed generation(DG) applications. In this paper Reverse voltage(RV) multilevel topology is proposed, which has reduced number of switches, electromagnetic interference & increased efficiency. This work focused on operation & integration of a singlephase RV multilevel inverter with photovoltaic(PV) sources. PV system is made to operate with maximum power output at a point know as maximum power point(MPP).In this paper a fuzzy logic controller is used as MPPT controller. The proposed work is verified through simulation using MATLAB/SIMULINK
