Abstract
A means of increasing the corona inception voltage (CIV), and thereby increasing the operating voltage, of film/foil capacitors is described. Intentional venting of the capacitor encapsulation improves the corona inception voltage by allowing internal voids to equilibrate with the ambient environment.
Claims8
A single or multi-section film/foil wound capacitor with one or more vent holes in the encapsulation material to intentionally make the part non-hermetic.
