摘要：
A series PV arc fault detection method and apparatus demodulates a current signal provided by a DC power source to an inverter to eliminate a DC component and periodic noise. Autocorrelation coefficients are generated from the demodulated current signal to monitor noise energy and variation and, based on the noise energy, a determination is made if an arc fault has occurred.
