1. An exciter assembly for supplying power to a superconducting load disposed within a cryogenic region of a rotating machine, the exciter assembly comprising:

  • a transformer having a primary winding and a secondary winding, one of the primary and secondary windings being positioned in a rotational reference frame relative to the other of the primary and secondary windings;

    a sensor which provides a control signal indicative of the flow of field excitation current to the superconducting load; and

    a current regulator which is disposed in the rotating reference frame and, on the basis of the control signal, regulates the field excitation current to a predetermined value.
