Harmonics Elimination in Grid Connected Single Phase PV Inverter

Mr. S. Arul Murugan, Mr. A. Anbarasan., M.E., (Ph.D.)

In this project, a simple single phase gridconnected photovoltaic (PV) inverter topology was implemented, this topology will not inject any lower order harmonics into the grid due to high-frequency pulse width modulation operation. The novel design of inverter that mitigates the lower order harmonics is presented in this project. A proportional-integral (PI) controller are implemented in order to overcome the lower order harmonic distortions. Low total harmonic distortion less than 5% have been achieved. The complete design has been validated with MATLAB software and the overall system operation is observed
