Detection of Inverter Leakage Current Based on Harmonic Extraction

This paper mainly introduces a classification and extraction method of leakage current, and a method for suppressing leakage current. First, the two-stage BOOST+HERIC photovoltaic grid-connected circuit is used for simulation. Then, the measurement of the complete current is done on the result of the simulation. Based on the measured current, harmonic extraction is done. Finally, the leakage current is suppressed.
