Grid-Connected Inverter Fed from PV Array

Abstract

This manuscript presents a grid-connected two-level inverter. The presented inverter is controlled by SRFtheory with a PI controller. The two-level inverter switching pulses are generated from the space vector modulation technique. The main advantages of two-level inverters are less number of switches, low switching loss, low cost and, suitable for low power rating applications. Software called MATLAB/Simulink is worn to reproduce the depicted circuit. the inverter output voltage, grid voltage, grid current, and PV module voltage are all confirmed by the simulation findings.
