摘要： A generator system is configured to supply two phase excitation current from an exciter rotor to a main generator rotor. When driven by a variable speed prime mover, the 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 the main rotor windings to provide two-phase excitation current to the main rotor 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 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 variable speed analog current (AC) generator system includes a main generator unit in electrical communication with a rotary transformer. The main generator unit outputs a main output power signal, and the rotary transformer adjusts a frequency of the main output power signal. The variable speed analog current (AC) generator system further includes an electronic exciter controller in electrical communication with the rotary transformer. The exciter controller is configured to determine a desired frequency of the main output power and apply an exciter signal having an adjustable exciter frequency to maintain the main output power signal at the desired frequency.
