Claims

[Claim for Utility Model Registration] A current component dependent on the voltage obtained from the terminal force of the alternating current generator via the alternating current reactor and a current component dependent on the current of the alternator obtained via the power current transformer. The vector-synthesized current is rectified by a rectifier, and a portion of the rectifier output current is supplied to the field winding, and the remaining current is supplied to the field winding. The current is shunted to a semiconductor switch connected to the DC side of the rectifier that is controlled on and off, and the difference current between the rectifier output current and the field winding current at the edge of the semiconductor switch is connected in parallel to the field winding. The semiconductor switch is turned on and off by a current regulator that generates a two-position operating output signal by comparing the target value of the current absorbed by the current absorption circuit and applied to the generator terminal voltage regulator 5 with the actual value of the field winding current. At the same time as controlling, a voltage limiting element is connected in parallel to the field winding, and when the field voltage rises above the operating voltage of this voltage limiting element, this voltage limiting element becomes conductive and the field voltage changes to this operation. An excitation adjustment device for an alternator, characterized in that the voltage does not rise above the voltage level.
