    Abstract: The disclosed technology is a cryogenic static exciter. The cryogenic static exciter is connected to a synchronous electric machine that has a field winding. The synchronous electric machine is cooled via a refrigerator or cryogen like liquid nitrogen. The static exciter is in communication with the field winding and is operating at ambient temperature. The static exciter receives cooling from a refrigerator or cryogen source, which may also service the synchronous machine, to selected areas of the static exciter and the cooling selectively reduces the operating temperature of the selected areas of the static exciter.

The homopolar electrical machine has a single stationary superconducting field coil configured to create a magnetic field. A homopolar rotor is configured to rotate within the magnetic field such that a rotating magnetic field is created in a stationary winding by interaction of the rotating permeance wave produced by the homopolar rotor and the magnetic field produced by the single stationary field coil. The homopolar electrical machine is configured as a generator and produces electrical power for the portable power system.

    Abstract: A machine includes a rotatable rotor assembly having a number of salient poles. The machine further includes a stationary stator assembly having concentric inner and outer stators, at least one stationary superconducting field coil and at least one stator coil. The stationary superconducting field coil is disposed between the inner and outer stators and is mounted on at least one of the inner and outer stators.

The interaction between the stationary superconducting field coil and the rotating poles provides the only source of a time varying magnetic flux supplied to the stator coil.

    Abstract: A system and method for protecting a superconductor from a quench condition. A quench protection system is provided to protect the superconductor from damage due to a quench condition. The quench protection system comprises a voltage detector operable to detect voltage across the superconductor. The system also comprises a frequency filter coupled to the voltage detector. The frequency filter is operable to couple voltage signals to a control circuit that are representative of a rise in superconductor voltage caused by a quench condition and to block voltage signals that are not. The system is operable to detect whether a quench condition exists in the superconductor based on the voltage signal received via the frequency filter and to initiate a protective action in response.
