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 rotor assembly for use within a superconducting electric motor includes a superconducting winding formed of high temperature superconductor and during operation, generates a flux path within the rotor assembly; and a high permeability magnetic material, positioned within at least a portion of the flux path so as to decrease the overall reluctance of the flux path. The rotor assembly may include a support member having an internal volume and formed of a non-magnetic, high-strength resilient material. The support member supports on its outer surface the superconducting winding and within its internal volume, the high permeability magnetic material. The magnetic material may be in the form of a core member to provide the low reluctance portion to the flux path generated by the superconducting winding.

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.

The superconducting rotating machine includes a stator assembly, a rotor assembly configured to rotate within the stator assembly and having at least one HTS superconducting winding assembly which, in operation, generates a magnetic flux linking the rotor assembly to the stator assembly, and a refrigeration system for cooling the at least one superconducting winding. The superconducting rotating has a gap shear characteristic greater than 10 psi.

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.

The conductor includes a first support lamina, a second support lamina, an insert including a high temperature superconductor disposed between the first and second support lamina, and a filler material surrounding the insert that bonds the insert to each of the first and second support lamina. At the location between the first support lamina and second support lamina corresponding to the location of the insert, the width dimension of the filler material on each side of the insert is at least 10 percent of a width of the conductor. The conductor is configured to carry at least 600 Amperes per turn and have a C-axis tensile strength of at least 21 MPa.
