Due to the advantages of the high working reliability, low dielectric loss as well as light weight and the characteristic self-healing performance, metallized film capacitors (MFCs) are widely used in modern power electronic systems [1], [2], [3].However, with the increasing demands in harsh environments such as inverters of hybrid and electric vehicles …
A theory of self-healing (SH) in metallized film capacitors (MFCs) is introduced. The interruption of the filamentary breakdown (BD) current in the thin dielectric insulation occurs when the thermally driven increase of the series impedance in the electrode metallization destabilizes the BD plasma arc. The interruption process can be described as a switching …
