NOVELTY - The assembly (10) has two support elements (18) which comprise several conductors. Several power switching devices are coupled to the support elements. Capacitors (22) are coupled to the support elements. The conductors, the power switching devices, and the capacitors are electrically connected such that the power switching devices are connected in parallel with the capacitors.    USE - Power electronics assembly such as direct current- direct current (DC/DC) converter, DC power supply, and DC- alternate current (AC) (DC/AC) inverter for automotive propulsion system (claimed) in automobile. Uses include but are not limited to automobile such as sedan, wagon, truck, sport utility vehicle, two-wheel drive, four-wheel drive, all-wheel drive, flex fuel vehicle, and hybrid electric vehicle.    ADVANTAGE - As the capacitor bobbins are in close proximity to the switching devices and the low inductance bus is used to created by the laminar current flow provided by the power bridge, the total bulk capacitance is distributed for current sharing equally between the two modules, so that the housing and resin potting materials typically associated with bulk capacitors is not needed. As the bus is provided by the heavy layers in the conductors in substrate, the need for a bus structure to connect the capacitors to the modules, and any included fasteners are eliminated. The structure of the heavy layer circuit card along with the laminar bridging bus structure and the short distance from the bulk capacitor bobbins to the power modules reduces the overall inductance of the assembly. As the substrate is used as a power stage allows each half of the inverter, or one of the modules to be mounted and electrically connected by a single circuit card, the overall mass and volume occupied by the assembly is reduced. Hence the need for a separate housing and wiring harness for the current sensors which is often found in power electronics assemblies is reduced.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for automotive propulsion system.    DESCRIPTION OF DRAWING(S) - The drawing shows an isometric view of the power electronics assembly.
