Abstract

In a method for detection of an arc in a current path of a converter arrangement () for converting a DC input power to an output power, an arc is detected by sensing the current () in the current path by means of a current transformer (), filtering the current signal (') with an analog band pass filter (), converting the analog filtered current signal (″) into a digital current signal (′″), determining the harmonic content () of the digital current signal (′″) and then deciding whether an arc exists if the harmonic content () exceeds a threshold, where the threshold is determined at the beginning as a multiple of the average harmonic content during a certain period of time of the current signal.
