摘要
A process for increasing the excitation current, particularly when activating the alternator, whose rectified alternator voltage is regulated by way of a regulator, is provided. For regulating the alternator voltage, the regulator sets the excitation current of an excitation winding of the alternator. The regulator further receives a phase signal. A rapid increasing of the excitation current to a defined value takes place, during which the phase signal is analyzed simultaneously. This rapid increasing continues until the phase signal or a quantity derived therefrom meets a defined condition with respect to the alternator voltage. Therefore, a further increasing of the excitation current takes place, preferably at a rate of change reduced with respect to the previous rapid increase.
