ESTIMATION OF ARC RESISTANCE, INTERNAL INDUCTANCE AND ESR OF HIGH VOLTAGE CAPACITORS

Abstract

In this Paper estimation of arc resistance, internal inductance and Equivalent series resistance (ESR) of high voltage capacitors are presented. When high voltage capacitors are intended to use in pulsed power applications, there is a need to characterize capacitors in terms of internal inductance, arc resistance & ESR. Short circuit discharge tests on high voltage capacitors of various make are carried out to characterize the capacitors. The variance of arc resistance with discharge current is studied. Also the effect of capacitance on the ESR and the effect of ESR on the output current are studied
