Design methodology of power level modulation for DC series arc fault detection and extinguishing

초록

The widespread deployment of solar energy systems has caused DC series arc faults to occur more frequently. In this paper, a comparative analysis of the characteristics of PV panels and DC series arc faults are conducted. This study introduces an original detection scheme capable of identifying DC series arc faults while preserving PV system output. The algorithm has been implemented to detect and extinguish DC series arc faults in real time using the DC/DC converter. The performance of the proposed method has been verified via both simulation studies and experimental measurements.
