Abstract

Abstract A laminated buss bar comprised of a pair of elongated flat conductors separated by an incorporated dielectric/electrode structure, the dielectric/electrode structure being sandwiched between the flat conductors on the opposite sides thereof, and a method of manufacture thereof. The buss bar is formed by depositing a flat layer of dielectric material on the inwardly facing surface of a first flat conductor and then forming an electrode of conductive material on the deposited layer of dielectric material. The inwardly facing surface of the first flat conductor also serves as one electrode of a capacitor. Subsequently, the formed conductive material electrode electrically and mechanically contacts the inwardly facing surface of a second flat conductor. Accordingly, the formed conductive material electrode, dielectric material, and one of the pair of elongated flat conductors form a capacitor.
