| 摘要 |
The invention relates to an alternator comprising: an alternator stator (2) having a main armature winding (7) delivering an output voltage, at least one auxiliary winding (3), and an exciter field winding (5) supplied by the auxiliary winding(s), a regulator (20) for regulating the output voltage of the alternator, and an alternator rotor (8) comprising an exciter armature winding (6), a rotating field winding (4) supplied by the exciter armature winding (6) and a circuit (10) for controlling the power supply to the rotating field winding (4), configured for maintaining the amplitude of the output voltage of the alternator at a predetermined level while controlling the power supply to the rotating field winding (4) in response to a control signal coming from the voltage regulator (20), the auxiliary winding(s) (3) generating a voltage due to their exposition to a variable magnetic field generated by the rotating field winding (4). |
