Multilevel inverter is one of the most recent and popular type of inverter founds its applications in the system based on renewable energy.This paper describes a new Single-phase seven level inverter topology for solar photovoltaic (PV) system using a carrier based PWM control scheme. This new topology has reduced number of switches for an increased number of levels when compared to conventional seven-level multilevel inverter. Here CPWM switching scheme is used to control the switches in this multilevel inverter and this inverter is fed from a solar PV. In this proposed topology, six power electronic switches are used for a seven-level inverter. By using this inverter topology, the harmonics is reduced and efficiency is enhanced significantly. Simulation work is done using the MATLAB/SIMULINK software which validates the proposed method and finally Total Harmonic Distortion is analyzed.
