6 FAQs about [Photovoltaic inverter waveform analysis]

How can a photovoltaic inverter influence background harmonic characteristics?

Taking the typical grid symmetrical harmonic −5th, +7th, −11th and + 13th order harmonic as an example, the impedance network and the definition of harmonic amplification coefficient can be used to analyze the influence of photovoltaic inverter on the corresponding background harmonic characteristics.

How a PV Grid connected inverter generates output harmonics?

The output harmonics of the PV grid-connected inverter are generated under the action of grid voltage harmonics, resulting in corresponding harmonics of its output current. The fundamental reason is that the output harmonics of the inverter are generated by the excitation of harmonic voltage source.
