<p>PURPOSE:To obtain the AC output of the prescribed frequency irrespective of the variation in the rotating speed of a prime mover by wiring the stator coil of an exciter in a distributed winding, serially connecting the unit coils, controlling a control switching element corresponding to the unit coils and outputting a sinusoidal AC. CONSTITUTION:A rotor 3 of a generator 2 and a rotor 5 of an exciter 4 are fixedly secured to a counterclockwise rotational shaft 1 coupled directly with a prime mover, and stators 6, 7 of the generator 2 and the exciter 4 are provided corresponding thereto. A rotor coil 5a of the exciter 4 is connected in reverse phase to the rotor coil 3a of the generator 2. The unit coils C1-C12 of the exciter 4 are alternately connected in series, and connected with switching elements S1-S12. The elements S1-S12 are controlled to supply a sinusoidal AC from the rotor coil 3a to the rotor coil 3a of the generator 2.</p> |
