1. A controlled frequency generating system (CFG) comprising:

  • a main generator;

    an exciter driven by a shaft common with the main generator;

    a bi-directional controller that extracts excitation power from an output of the main generator when the CFG operates at a rotational speed at which supplemental power input to the exciter is required; and

    the bi-directional controller extracts power from the exciter when the main generator operates at a rotational speed at which the exciter produces power in excess of excitation requirements.
