Power coupling devices for high-temperature superconductors

A power connection system comprising:

• a high-temperature superconductor (HTS) to receive a current from a power source, the HTS having an HTS conductor;
• an electrically conductive cable to supply an output current to at least one electronic equipment, the electrically conductive cable having an electrical conductor;
• and
• a power coupling device having:
• a first end interfaced with the HTS;
• a second end interfaced with the HTS;
• and
• a power coupling system comprising:
• a rotatably mounted shaft having a motor side and a generator side;
• wherein an input current from the HTS conductor drives a motor assembly to rotate the shaft and wherein rotation of the shaft causes a generator assembly to generate the output current, and wherein the generator assembly is thermally and electrically isolated from the motor assembly.

A power coupling device comprising:

• a housing to couple a high-temperature semiconductor (HTS) with an electrically conductive cable, the HTS having an HTS conductor and the electrically conductive cable having an electrical conductor;
• and
• a power coupling system housed within the housing, the power coupling system comprising:
• a rotatably mounted shaft having a motor side and a generator side;
• a motor assembly on the motor side;
• and
• a generator assembly on the generator side,
• wherein an input current from the HTS conductor drives the motor assembly to rotate the shaft and wherein rotation of the shaft causes the generator assembly to generate an output current, and wherein generator assembly is thermally and electrically isolated from the motor assembly.
