Abstract: A contactless power transfer system is provided. The contactless power transfer system includes a first power exchanger coil configured to exchange power. The contactless power transfer system also includes a first power converter operatively coupled to the first power exchanger coil and configured to convert a direct current power to an alternating current power at a system frequency. The contactless power transfer system further includes a controller configured to control an operating state of the first power converter to vary an alternating current power provided to the first power exchanger coil at the system frequency.

Abstract: An electric power system for a vehicle includes at least one electric machine, one or more power rectifiers, and a plurality of DC channels. The at least one electric machine includes a plurality of tooth-wound multi-phase windings that are substantially magnetically decoupled, and the at least one electric machine is mechanically balanced even if one of the plurality of windings is de-energized. The one or more power rectifiers are configured to produce rectified power from the power generated by the at least one electric machine. The plurality of DC channels are formed after the at least one power rectifier and are configured to provide DC power to one or more loads within a vehicle.

Abstract: A power distribution system in operative association with a source and a plurality of loads includes a converter, a power distribution unit including a plurality of solid state power controllers and configured to provide power from converter to plurality of loads, and a fault protection unit operatively coupled to converter, power distribution unit, or both. The fault protection unit includes a sensor configured to sense current at output terminal of at least one of power distribution unit and converter and a controller configured to compare sensed current with a corresponding threshold value of current, identify presence of a fault in at least one of plurality of loads, power distribution unit, and converter based on comparison, and activate a desired protection scheme to provide fault ride through during the presence of the fault.
