摘要： When driven by a variable speed prime mover, a generator system provides relatively constant frequency AC power by independently controlling the main rotor flux rotational speed. The generator system includes an exciter stator that induces current in the exciter rotor windings at a desired frequency and phasing. The exciter rotor windings are electrically connected to and located in a common core as the main rotor windings to provide two-phase excitation current to the main rotor windings. The exciter stator winding is also located in a common core as the main generator stator windings. Excitation is supplied to the exciter stator from an exciter controller, which controls the frequency and phasing of the exciter excitation, based on the rotational speed and rotor position of the generator, to maintain a constant output frequency. The exciter frequency control function of the exciter controller may be eliminated when the generator system is driven by a constant speed prime mover or when a narrow band variable frequency output is required.

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.

摘要翻译： 受控频率发生系统（CFG）可以由主发电机和由公共轴驱动的励磁机构成。 可以从公共轴提供励磁功率; 与可能需要独立激励电源的现有技术系统不同。 在控制主发电机的输出电压和频率的同时，双向控制器从主发电机输出端提取功率，并可在提供某些转速时提供提取的功率以补充激励功率。 当在其他转速下，激励器产生过量功率时，控制器可从激励器提取功率。 提取的过剩功率可以被传送到主发电机的输出端，以保持期望的输出功率水平处于期望的频率，而与CFG的转速无关。

摘要： A high frequency starter-generator system uses an electric machine design that does not employ rotating rectifiers installed on the rotor. The output frequency of such a starter-generator is increased by about 200% as compared with a conventional starter-generator with the same number of poles operating in the same speed range. This design allows significant weight and volume reductions of the electric machine while its reliability is increased. The present invention may find application in any starter-generator application, including more electric architecture-type aircraft designs currently in development.
