Abstract: A closed ferromagnetic housing has a pair of access ports and a center ferromagnetic post extending from and between opposite ends thereof. At least one conductor, contained within and completely surrounded by the closed ferromagnetic housing, is wound around the center ferromagnetic post such that the closed ferromagnetic housing, center ferromagnetic post, and at least one conductor form an inductor in which the ferromagnetic housing and the center ferromagnetic post define a core of the inductor and the at least one conductor defines a coil of the inductor. The access ports are configured to permit flow of coolant into the closed ferromagnetic housing and around the center ferromagnetic post to cool the at least one conductor.

Abstract: A power module includes one of more bus capacitors and one or more power switching modules. The bus capacitors and power switching modules have positive and negative terminals. The positive terminals of the bus capacitors are arranged diagonally opposite to the positive terminals of the power switching modules. The negative terminals of the bus capacitors are arranged diagonally opposite to the negative terminals of the power switching modules. A laminated busbar assembly connects a positive conducting layer to the positive terminals and a negative conducting layer to the negative terminals. The laminated busbar assembly includes sets of tabs arranged diagonally opposite one another to match the arrangement of the terminals.

Abstract: A DC to AC inverter includes a plurality of power units. Each power unit has a pair of switches, a DC linking capacitor, AC and DC bus bars, and a monolithic insulating material that encapsulates the switches, capacitor and bus bars. Each switch is sandwiched between one of the AC bars and one of the DC bus bars. The monolithic insulating material exposes external surfaces of at least one the bus bars sandwiching each switch.

Abstract: A traction powertrain system of an electrified vehicle includes a power electronics module and a controller. The power electronics module, such as in the form of an inverter, is configured to drive a traction motor with power from a traction battery via a DC-link capacitor. The controller has an on-board power source, such as in the form of a super capacitor. The controller is configured to, in response to detecting an event in which the DC-link capacitor is to be discharged, use power from the on-board power source for controlling the power electronics module and control the power electronics module to operate in a manner causing the DC-link capacitor to be discharged.
