Abstract
A system for converting energy includes a doubly-fed induction machine including a rotor having a plurality of rotor windings, and a stator having a plurality of stator windings. The system also includes a power conversion unit in electrical communication with the plurality of rotor windings, where the power conversion unit is configured to excite the plurality of rotor windings with an alternating current. The system also includes a relay unit in electrical communication with the plurality of stator windings, where the relay unit is configured to electrically interconnect a plurality of terminals of the plurality of stator windings. The system also includes a controller in electrical communication with the power conversion unit and the relay unit, where the controller is programmed to adjust an operation of the doubly-fed induction machine using the power conversion unit and the relay unit based on the rotational velocity of the rotor.
