In examples, provided are leadless power couplers that include (1) a thermal insulating system having an outer wall and an inner wall, (2) a first electrically conductive winding located outside the thermal insulating system, where the first electrically conductive winding is configured to create a varying magnetic field, (3) a plurality of second electrically conductive windings located inside the thermal insulating system and configured to couple to the varying magnetic field, the plurality of second electrically conductive windings being superconductors, (4) a plurality of cryogenic rectifiers, each cryogenic rectifier being coupled to a respective second electrically conductive winding in the plurality of second electrically conductive windings, and (5) a plurality of cryogenic cables coupled between respective outputs of the plurality of cryogenic rectifiers and respective loads.

Systems and methods for leadless power coupling for cryogenic environments

A cable termination comprising an upper cryostat chamber containing a liquid cryogen and a lower cryostat chamber containing a gaseous cryogen to maintain dielectric integrity and thermal management of an electric connection. A gaseous cryogen recirculation system may cause the gaseous cryogen to flow through the lower cryostat chamber and a power cable enclosure.

Termination for gas cooled cryogenic power cables

A heat sink and method for gaseous cooling of superconducting power devices. Heat sink is formed of a solid material of high thermal conductivity and attached to the area needed to be cooled. Two channels are connected to the heat sink to allow an inlet and an outlet for cryogenic gaseous coolant. Inside the hollow heat sink are fins to increase metal surface in contact with the coolant. The coolant enters through the inlet tube, passes through the finned area inside the heat sink and exits through the outlet tube.
