Abstract: An apparatus for use in a wireless power transfer system (100) that provides a first AC voltage (224) from a first converting unit (204) via a primary coil (228) of a contactless power transfer unit (208). The first AC voltage is managed by a control unit (206) coupled with a second transceiver (216). The apparatus comprises a secondary coil (230) configured to wirelessly receive an input power having the first AC voltage (224) from the primary coil (228) and provide the input power to a second converting unit (210). The second converting unit (210) is configured to receive the input power from the secondary coil (230) and to convert the first AC voltage (224) of the input power to an output DC voltage (238). The input power having the output DC voltage (238) is provided to an electric load (232). The apparatus comprises a first transceiver (214) configured to communicate a voltage signal to the second transceiver (216). The voltage signal is representative of the output DC voltage (238) across the electric load (232). The voltage signal is communicated to cause the control unit (206) to regulate the first AC voltage (224) if the output DC voltage (238) across the electric load (232) is greater than a voltage reference value. The apparatus comprises a switching unit (212) configured to regulate the input power having the output DC voltage to protect one or more components of the apparatus.

Abstract: A circuit interrupter for interrupting current on a line conductor is provided. The circuit interrupter includes separable contacts, a trip mechanism, a bimetal, a microprocessor, a series arc detection sequence, a low-pass filter circuit, and a high-pass filter circuit. The trip mechanism selectively opens the separable contacts when activated. The series arc detection sequence is resident on the microprocessor and includes a plurality of series fault detection algorithms. The low-pass filter circuit provides a low-pass signal to the series arc detection sequence. The high-pass filter circuit provides a high-pass signal to the series arc detection sequence. The sequence selects a particular algorithm from the plurality of algorithms based on the low-pass signal. The sequence calculates a plurality of statistical features from the high-pass signal and sends an output signal to activate the trip mechanism based on a comparison of the plurality of statistical features to the particular algorithm.

Abstract: A sub- sea power transmission/distribution network includes a plurality of standard proven power converter building blocks (12) on each of the power source side (16) and the sub- sea load side (22). The power source side converters and the sub -sea load side converters are each configured to provide a modular stacked dc (MSDC) converter architecture. The power source side converters are further configured to share the load equally or in proportion to their individual power ratings. The configurations are based on corresponding droop curves representative of MSDC link current magnitude data and average output voltage data of the power source side converters.
