In pulsed power systems, metallized polypropylene film capacitors (MPPFCs) facilitate the operation of the polypropylene film with a relatively small margin to its dc breakdown strength. The insulation resistance (IR) is one of the important factors that result in the reduction of the energy efficiency, as it represents a current leakage path through the dielectric. This paper concentrates on the...
Metallized polypropylene film capacitor (MPPFC) has characteristics of high energy density and high reliability due to its self-healing capability. The insulation resistance (IR) of capacitor applies a leakage path through the dielectric and would exert negative influences on the efficiency of the pulsed power system. This paper mainly concentrates on the leakage phenomenon in MPPFC by the measurement...
