    摘要： A stacked busbar assembly includes two or more busbar subassemblies, each including a plurality of busbars having one or more power semiconductor devices bonded thereto (e.g., IGBTs, power diodes, and the like). Each busbar has an internal integrated cooling system including one or more fluid channels in communication with an inlet and an outlet. The busbar assemblies are stacked such that their respective inlets and outlets are aligned and a coolant may then flow in parallel therethrough.

    摘要： An inductive charging coupler for use in an inductive charging apparatus used to charge a battery. The charging coupler is insertable into a charge port that is coupled to the battery. The charge port comprises a housing, an opening into which the charging coupler is inserted, and a ferrite core surrounded by secondary windings. The charging coupler comprises a housing having a hollow disk-shaped section with substantially flat opposed surfaces and a tapered handle extending therefrom. An opening is disposed through each of the flat opposed surfaces. A center magnetic core is disposed in the opening and has opposed flat surfaces that are substantially coplanar with the substantially flat opposed surfaces of the housing. A primary winding is disposed in the hollow disk-shaped section around the center magnetic core. The coupler has the shape of a paddle and is designed to give a vehicle operator a sense of safety when transferring electric power to the battery of an electric vehicle, for example.

    摘要： A fuel cell system that employs a matched battery that matches the battery voltage to a fuel cell power bus voltage so as to eliminate the need for a DC/DC converter. The internal characteristics and parameters of the matched battery allow it to operate over the large load dependent voltage swing of the fuel cell, and prevent the battery state of charge from going below a damaging value. The battery type, number of battery cells and the battery internal impedance are selected to provide the desired matching. In one embodiment, the battery is a lithium ion battery. The system also includes a diode electrically coupled to the power bus line and a by-pass switch electrically coupled to the power bus line in parallel with the diode. The by-pass switch is selectively opened or closed to allow the fuel cell stack to recharge the battery and prevent the battery from being overcharged.

    摘要： A cooling device is provided for liquid cooling a power semiconductor device. The device includes a coolant diverter for guiding liquid coolant to the power semiconductor device. The coolant diverter has a first plate for dividing the coolant diverter into a first cavity and a second cavity. The second cavity positioned adjacent the power semiconductor device. The first plate further includes an opening to fluidly couple the first cavity with the second cavity such that the liquid coolant flows into the first cavity, through the opening in the first plate, and into the second cavity to cool the power semiconductor device. The first cavity has a cross-sectional area that generally decreases in a downstream direction, and the second cavity has a cross-sectional area that generally increases in the downstream direction.
