摘要： An electronics assembly includes a plurality of planar conductive metal sheets including a first conductive metal sheet, a second conductive metal sheet attached and electrically coupled to the first metal sheet, and a third conductive metal sheet attached and electrically coupled to the second metal sheet. The second metal sheet is located between the first and third conductive metal sheets. Air gaps are defined in the plurality of planar conductive metal sheets to form metal traces that define electrically isolated conductive paths from an outer surface of the first conductive metal sheet to an outer surface of the third conductive metal sheet in a multilevel conductive wiring network. The multilevel conductive wiring network can be attached and electrically coupled to a microchip and to one or more capacitors to form a power converter.

摘要： An inductor component includes an element body, a coil disposed in the element body, and a non-magnetic insulating layer configured to cover at least part of the coil. The element body has a first magnetic layer and a second magnetic layer stacked in order along a first direction. The coil has an inductor wiring extending along a plane orthogonal to the first direction between the first magnetic layer and the second magnetic layer. In a first section orthogonal to an extending direction of the inductor wiring, the inductor wiring has a top surface facing the first direction, a bottom surface facing a second direction as a reverse direction of the first direction, a first side surface facing a third direction orthogonal to the first direction, and a second side surface facing a fourth direction as a reverse direction of the third direction.

摘要： A vehicle, a vehicle power electronics assembly, and a method of packaging and cooling an inductor assembly are provided. The vehicle has a vehicle electrical system with a variable voltage converter (VVC) and an inductor assembly. The inductor assembly has a core and a winding. A bobbin is connected to and surrounds an outer perimeter of the inductor assembly. The bobbin defines an inlet, an internal fluid passage, and a series of nozzles. The nozzles in the series of nozzles are spaced apart from one another about the bobbin and are positioned to spray fluid directly onto the winding. A fluid system is connected to the inlet to provide pressurized fluid to the inlet.
