ABSTRACT:
A system and method are provided to manage the excitation of an automobile alternator through the use of its regulator which delivers to the inductor of the alternator a pulse width modulation excitation signal. The regulator receives, from an external management unit, a pulse width modulation excitation control signal with a frequency less than that of the excitation signal. The regulator delivers an excitation signal with a pre-programmed cycle ratio for a sufficient duration to enable the regulator to determine the control information carried by the control signal from the management unit. The regulator continues the excitation signal with the pre-programmed cycle ratio until receipt of instruction from the management unit to regulate the battery voltage.
