    摘要: The invention provides an apparatus for supplying power to superconducting loads includes a current source, a cryogenic region (e.g., a cryogenic chamber), a first switching device in series between the current source and a superconducting load, and a second switching device in parallel with the superconducting load. The switching devices are arranged so that, when the first is closed and the second is open, recharging current is supplied to the superconducting load. The second switching device serves as a shunt. When it is closed and the first is open, current recirculates through the persistent (or partially persistent) superconducting load. The invention also provides a superconducting magnet incorporating such a power supply.

    摘要: A method of maintaining a desired level of sub-transient reactance in a superconducting machine includes specifying a desired level of sub-transient reactance. A stator assembly is produced that includes at least one stator coil assembly having a first predefined length. A rotor assembly is produced that is configured to rotate within the stator assembly. An asynchronous field filtering shield, having a second predefined length that is less than the first predefined length, is positioned between the stator assembly and the rotor assembly. The desired level of sub-transient reactance is achieved by adjusting either the first predefined length or the second predefined length.

    摘要: A superconducting conductor and its method of manufacture includes an electrical conductor having a thermal conductor attached to and along a length of superconductor member and separated from the superconductor member by an electrically-insulative material. The member may include a length of superconductor composite having superconducting material and a non-superconducting, electrically conductive matrix material. The electrical conductor is configured to control the manner in which the superconductor transitions from its superconducting state to its non-superconducting (i.e., normal) state due to, for example, a fault current condition. The electrically-insulative material has a thickness for allowing heat from the superconductor to be conveyed to the thermal conductor. The superconducting conductor may be used in conjunction with a superconducting current-limiting device.

    摘要: An electric coil includes bifilar pancake coils electrically connected to an adjacent pancake coil so that current flowing in adjacent turns of adjacent pancake coils flows in opposite directions at all radial region of the coil assembly. The superconducting fault current limiter is configured to provide a minimized inductance and low resistance in a normal state of operation. On the other hand, when a fault current exceeds a predetermined threshold, the resistance increases to a level sufficient for limiting the flow of fault current to a desired level until a circuit breaker connected within the electrical system opens the circuit.
