   High Current Aging Test for Metalized Polypropylene Film Capacitors Having Different Geometric Shape

Abstract: In this study we examine the phenomenon of aging of Metalized PolyPropylene (MPP) film capacitors. The study is performed for three series of capacitors having the same capacitance but different geometry. The three series of capacitors are subjected to electric stresses which consist in passing a strong sinusoidal current through the component under test. The test current is selected in such a way as not to exceed, in the worst of cases, maximum rating temperature of the element, namely 90 °C. Each capacitor is tested separately and the few thousand hours of test show a decrease of the capacitance for the long capacitors. This is due to the fact that, under the same electric stresses, long capacitors heat up more as compared to the flat one. The results of these tests would allow us to have a clear idea about the relationship between the geometry of a metalized polypropylene film capacitors and its reliability.

   Supercapacitors Electrical Behaviour for Power Electronics Applications

Abstract: Recent developments in the field of supercapacitors have led to the achievement of high specific energy and high specific power devices. Due to capacitances of several hundred farads and serial resistances of less than one milliohm, these new components are suitable for energy storage in high power electronic applications, especially in the field of management of embarked electrical power (hybrid power sources, energy recovery). This paper presents theory, characterisation and experimental validation of an accurate electric double-layer supercapacitor model based on the physics of phenomena governing charges storage, which theoretically leads to a transmission line with voltage dependant distributed capacitance.
