Abstract: An electrical system includes a power electronics system and a bus bar coupled to the power electronic system. The power electronics system includes a switching device configured to selectively connect and disconnect. The bus bar includes a first conductive layer and a second conductive layer. The first conductive layer is disposed directly adjacent a first insulation layer, wherein the first conductive layer is configured to conduct a first polarity of electrical power to, from, or both the power electronics system. The second conductive layer is disposed directly adjacent the first insulation layer, and is configured to conduct a second polarity of electrical power opposite the first polarity to, from, or both the power electronics system. The first conductive layer comprises a first thickness half a second thickness of the second conductive layer.

Abstract: A power module includes an input bus, a switching device, and an output bus. The input bus includes a first coating of a high permeability magnetic conductive material and is configured to receive input direct current (DC) electrical power from an electrical power source. The switching device is electrically coupled to the first input bus, and is configured to selectively connect and disconnect to facilitate converting the input DC electrical power into output alternating current (AC) electrical power. The output bus includes a second coating of the high permeability magnetic conductive material, and is electrically coupled to the first switching device. The output bus is configured to supply the output AC electrical power to an electrical load.
