Abstract:
1. A method of compensating for a voltage dip in an output voltage of an alternator of a motor-vehicle, due to one of connection of a load to the motor-vehicle and a change in a speed of the motor-vehicle, with the aid of an alternator regulator which provides a control signal having a duty factor, the method comprising: acquiring, after the occurrence of the voltage dip, parameters describing an instantaneous operating point of the motor-vehicle alternator; initially increasing the duty factor of the control signal of the alternator regulator by a differential amount which is set as a function of the acquired instantaneous operating point, whereby the increased duty factor of the control signal increases an excitation current of the motor-vehicle alternator; and subsequently limiting the rate of increase of the duty factor of the control signal to a selected maximum rate.
