Abstract: A wireless power transfer system is disclosed. The wireless power transfer system includes a first converting unit configured to convert a first DC voltage of an input power to a first AC voltage. Further, the wireless power transfer system includes a contactless power transfer unit configured to receive the input power having the first AC voltage from the first converting unit and transmit the input power. Also, the wireless power transfer system includes a second converting unit configured to receive the input power from the contactless power transfer unit and convert the first AC voltage of the input power to a second DC voltage. Furthermore, the wireless power transfer system includes a switching unit configured to decouple the second converting unit from the contactless power transfer unit if the second DC voltage across the electric load is greater than a first threshold value.

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: 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.
