Abstract: A wind turbine includes a superconducting generator having an armature and a superconducting field winding set. The armature includes at least one multiphase armature winding set having a plurality of armature windings. The superconducting field winding set is separated by a gap from the armature. The superconducting field winding set includes a plurality of field windings, wherein one of the armature winding set and superconducting field winding set is connectable to rotate with a rotating component of the wind turbine and another of the armature and the superconducting field winding set being non-rotating. The wind turbine also includes a controllable power converter coupled to the at least one multiphase armature winding set and a controller configured to control switching operations of the controllable power converter to effect a phase shift among the plurality of armature windings.

Abstract: An energy conversion system includes a low-impedance generator having at least one armature winding set. The armature winding set includes a plurality of single-phase coils. The system also includes a current source converter assembly electrically coupled to an armature of the generator. The current source converter assembly includes at least one current source converter that includes a current source rectifier coupled to a current source inverter via a DC link and at least one capacitor across the plurality of single-phase armature coils. The capacitor(s) of the current source converter(s) is configured to absorb high frequency components of current pulses generated by the current source converter so as to minimize current ripple in a current applied to the plurality of single-phase coils.

Abstract: A power converter apparatus comprises a set of switching elements communicatively coupled with a set of gate drive circuits. Each gate drive circuit is configured to provide a respective drive signal to a corresponding switching element, each switching element being switchably responsive to the respective drive signal. The apparatus includes a controller module configured to control an output state of the power converter, and selectively change one of a respective gate resistance and a respective gate current of a corresponding subset of the gate drive circuits based on the output state of the power converter.
