A single phase seven level inverter topology for photovoltaic application

Abstract

A single phase seven level inverter topology with fewer components using proportional integration controller is presented in this paper. The pulse width modulation is employed to generate gating signals for power switches. The proposed topology can be implemented for three phase application. The Separate dc sources can be replaced by solar PV arrays. The complete system is simulated using MATLAB/SIMULINK™ for simulation results and dsPIC33EP microcontroller is used to generate gating signals, hardware results are presented to check the performance of the inverter
