Device for setting the output voltage in a three-phase alternator
First Claim
1. A device for regulating the output voltage of a rotary current generator with stator windings and an exciter winding, with a voltage regulator which includes a control stage with a first integrated regulating circuit and a power stage with a regulating transistor, wherein the control stage influences the regulating transistor to influence the current through the exciter winding in such a way that the output voltage is kept at a predeterminable value, characterized in that the first integrated circuit (IS1) is connectable via a semiconductor switch to the terminal (B+) of the rotary current generator (10), and the semiconductor switch includes an integrated circuit (IS2), which triggers a smart power high-side switch (31).

Abstract
A device for controlling the output voltage of a rotary current generator is disclosed, in which a generator without exciter diodes is used, and the exciter current is furnished by the rectifier bridge of the generator. The exciter current is regulated with the aid of a first integrated circuit. In addition, a smart power high-side switch, which is regulated by an integrated circuit (IS2), is located in the exciter current circuit.
