摘要：
A photovoltaic (PV) system includes a string of at least one PV module, and an arc fault detector (AFD) electrically coupled to the string. The AFD is configured to detect a non-DC electrical current that occurs within the string, and cause electrical contacts within the PV system to open as a result of the detected non-DC electrical current. The system includes a capacitor electrically coupled to the string and to the AFD such that the non-DC electrical current passes through the AFD and the capacitor.
