  • Patent number: 9595901
    Abstract: The invention relates to a method for regulating the output voltage of the alternator of a generator set, said generator set including a heat engine driving the alternator, the alternator including a rotor having a pole wheel. Said method includes the following step: detection of an increase in the power at the outlet of the alternator, and in the event of a detected increase, the value of the current in the polar wheel is modified in such a way as to temporarily bring the output voltage of the alternator to a value lower than the value before the detection of the increase in power, with the aim of decreasing the level of torque required from the heat engine.
