  • Patent number: 8810978
    Abstract: Disclosed herein is a Superconducting Fault Current Limiter (SFCL) for suppressing a bus voltage drop in an electric power system. A primary winding, a secondary winding, and a tertiary winding are wound around an identical iron core, and a superconductor is connected to any one of the primary winding and the secondary winding. A first switch is connected to any one of the primary winding and the secondary winding and is configured to be opened so as to separate a faulty section when a fault current is generated and to be shorted when the fault current is eliminated. A second switch is connected in series to the tertiary winding and is configured to be shorted so as to stably supply power when the fault current is generated and to be opened when the fault current is eliminated.

  • Publication number: 20110234161
    Abstract: The present disclosure includes an adapter and associated method of use for mobile unit (MU) charging and communication that enables multiple connector types to be utilized with a single charger or charging station. The adapter enables standardization of a connector scheme on newer MUs while maintaining compatibility with current or older MU devices. Specifically, the adapter resides between the MU and a charging device or station. The adapter may include various connector features mimicking connectors of various different MUs, thus allowing it to interface with a device of a different connector design. Advantageously, the adapter enables enterprises to deploy various cradles throughout facilities and achieves universal connections for a plurality of different MUs. In an exemplary embodiment, the adapter provides connectivity between various MUs and their associated cradles and a hook and pivoting latching system.

  • Patent number: 7679867
    Abstract: A magnetic flux coupling-type superconducting current limiter is capable of protecting lines more effectively by winding reactors of a primary coil and a secondary coil in series in the structure where the primary coil and the secondary coils are wound in parallel in the conventional magnetic flux-lock type current limiter to increase a linked flux generated from an iron core. An electric conducting current which rapidly increases when a fault occurs is divided into the secondary coil and a superconducting coil to decrease a load on the superconducting element and it is opened more rapidly than the existing superconducting current limiter during a quench time such that it better limits a fault current.
