Reduction of waveform distortion in grid-injection current from single-phase utility interactive PV-inverter

As the natural behavior of energy source and design characteristic, the current generated by a grid-interactive PV-inverter may contain harmonics. This distortion component will be carried on from the PV-inverter during injection power into the grid. Excessive harmonics in a grid will lead to a vari...
