Abstract：The metallized polypropylene film capacitor(MPPFC) is one of the key components in pulsed power systems. The insulation resistance(IR) is one of the important factors resulting in the reduction of the capacitor energy efficiency in that it applies a current leakage path. This paper concentrates on the leakage phenomenon in the MPPFC by the measurement and analysis of the IR. The results indicate that the time constant(called equivalent IR) is extremely sensitive to the electric field and crystallinity Finally, theoretical calculation of equivalent IR based on the Poole-Frenkel effect match well with the experimental results.
