Abstract
The invention relates to a voltage regulator () for a motor vehicle alternator (). The device comprises a control module (I) for controlling an excitation current (lexc) in an excitation winding () of the alternator () according to a difference () between a setpoint voltage (DO) and a control voltage (Dbat) of an on-board network (). The on-board network () of the vehicle is powered by a battery () to which the alternator () is connected. According to the invention, the voltage regulator () further comprises a safety module () that monitors the control voltage (Ubat) and which is separate from the control module (I). In a particular embodiment, the control module (I) and the safety module () are connected electrically by external bonding interconnections.
