Claim Text:
1. A method for increasing an excitation current of a polyphase alternating-current alternator connected to an on-board power supply system of a motor vehicle, wherein a regulator is connected to the alternator and a rectifier is connected to an output side of the alternator, and wherein the regulator is configured to receive a phase signal, the method comprising the acts of: generating, by the rectifier, a rectified alternator voltage that is regulated by way of the regulator; increasing, by the regulator, the excitation current of an excitation winding of the alternator at an initial rate of change, wherein the excitation current is based on a duty factor of an output stage of the regulator; determining, by the regulator during said increasing of the excitation current, whether at least one of the phase signal and a quantity derived from the phase signal satisfies a condition relating to a present rectified alternator voltage; and continuing, after the at least one of the phase signal and the quantity derived from the phase signal satisfies the condition, to increase the excitation current to a target value at a rate reduced with respect to the initial rate of change.
