Abstract
A generator device with a generator regulator and a generator unit having a generator and a rectifier arrangement. The generator regulator has an operating voltage connection and a phase voltage connection. Furthermore, if during a control intervention of the phase voltage the DC voltage applied to the operating voltage connection exceeds a predefined limit for a predefined period of time, the generator regulator deactivates the control intervention of the phase voltage.
Claims7
A generator device comprising:
- a generator regulator and a generator unit having a generator and a rectifier arrangement, the generator regulator having a phase voltage detector detecting a phase voltage, an operating voltage connection, and a phase voltage connection,
- wherein a control intervention of the phase voltage is initiated based on the detected phase voltage, and wherein if, during the control intervention of the phase voltage, the DC voltage applied to the operating voltage connection exceeds a predefined limit for a predefined period of time, the generator regulator deactivates the control intervention of the phase voltage.
