DC arc faults are dangerous to photovoltaic (PV) systems and can cause serious electric fire hazards and property damage. Because the PV inverter works in a high−frequency pulse width modulation (PWM) control mode, the arc fault detection is prone to nuisance tripping due to PV inverter noises. [pdf]
Abstract: DC circuits such as battery storage systems bear an inherent risk of fire through electric arc faults. This paper reveals how different system parameters are linked to the arc fault risk and which of them are useful for detection. [pdf]
