Abstract
Abstract Various structures for and methods of constructing miniaturized high capacitance bus bars are presented. The bus bars incorporate discrete high capacitive elements between a pair of bus bar conductors. Alternate arrangements are presented wherein the capacitive elements are maintained in electrical contact with the conductors while avoiding the development of short circuits between the two bus bar conductors.
