摘要
A controlled frequency generating system (CFG) may be constructed with a main generator and an exciter driven by a common shaft. Excitation power may be provided from the common shaft; as distinct from prior-art systems which may require independent excitation power sources. While controlling the output voltage and frequency of the main generator, the bi-directional controller extracts power from a main generator output and may supply the extracted power to supplement excitation power when needed at certain rotational speeds. The controller may extract power from the exciter when, at other rotational speeds, the exciter produces excess power. The extracted excess power may be delivered to the output of the main generator to maintain a desired level of output power at a desired frequency, irrespective of speed of rotation of the CFG.
