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.

摘要： A synchronous electrical machine comprises a plurality of phases and detecting means arranged to detect an open-circuit fault in at least one of the phases of the synchronous electrical machine. Isolating means is arranged to isolate the at least one phase of the synchronous electrical machine with the fault. Phase shift means are arranged to produce a controlled phase shift between the voltage and the current within the remaining phases of the synchronous electrical machine so as to adjust the phase angle of the second harmonic powers produced by the remaining phases of the synchronous electrical machine such that the vector sum of the second harmonic power vectors of the remaining phases of the synchronous electrical machine is zero to eliminate torque ripple. The phase shift means is arranged to adjust the phase angle of all the remaining phases by the same predetermined angle to maximize the torque ripple-free power output of the synchronous electrical machine.

In this manner, the electrical power output of the generator, and its effect on fuel consumption, are reduced in response to supplying of the offset current. A source of electrical energy external to the electrical system of the motor vehicle is controlled by an electronic control unit coupled to the source of electrical energy. A power converter receives on and off commands from the electronic control unit in response to vehicle voltage measurements by the electronic control unit.

An exciter system such as this results in the capability to briefly increase the excitation in a simple, functionally reliable and space-saving manner, by inserting a forward-biased diode (22) into the exciter circuit, and by the capability to connect the second device (23) to the diode (22), in the reverse-bias direction, in order to feed the energy into the exciter circuit.
