Abstract
A low impedance, low noise laminated bus assembly for a high power switched converter that has a plurality of switch pairs including a -DC switch and a +DC switch for high speed switching to convert between an AC power line and a DC power storage device such as capacitors. The laminated bus assembly includes a first conductor plane having a plurality of AC bar conductors for each phase of AC power, a second conductor plane including a -DC bar conductor, and a third conductor plane including a +DC bar conductor. A dielectric layer is laminated between the first, second, and third planes. The circuit layout includes a plurality of electrical connections between the switches, the AC, -DC and +DC bar conductors, and the DC power storage device. Some of the electrical connections require that a coupling conductor pass through another bar conductor, which must therefore be insulated from the coupling conductor. Each bar conductor therefore has at least one insulated hole that includes an annular insulator through which the coupling conductor, which is a bushing, is inserted.
