Abstract:
A device for regulating a voltage at which an automobile battery is charged by an alternator, comprising:a control circuit including means for controlling an excitation of an inductor of the alternator as a function of a charging voltage and means for detecting a start of rotation of the alternator, the control circuit adapted to be activated and to emit an excitation signal only when the start of rotation of the alternator is detected; a power circuit including means for amplifying the excitation signals from the control circuit and means for generating a self-excitation signal; and an external management unit, connected externally to the control circuit and the power circuit, for transmitting different regulation parameters to the control circuit when the alternator is running and for delivering a control signal directly to the power circuit when the alternator is not running to cause the means for generating to generate the self-excitation signal.
