摘要： A regulator has a circuit generating an activation command by bringing, to a first voltage higher than a high reference voltage, a bidirectional line connected to a detection circuit for detecting a status of the activation command. The detection circuit comprises generation means for generating a fault signal from a flag indicating a failure of the alternator, linking the line to a ground by means of a switching element, thus bringing the line to a second voltage lower than a fault voltage lower than the high reference voltage, and the control circuit comprises detection means for detecting the fault signal. The control circuit further transmits a setpoint PWM signal having a maximum higher than the high reference voltage and a minimum lower than a low reference voltage higher than the fault voltage, a duty ratio of the setpoint signal being representative of a setpoint voltage (V0) of the regulator.

摘要： System (17) for managing a supply voltage (B+A) of an onboard electrical network of a motor vehicle comprises a device (2, 4, 9, 16) for regulating the supply voltage and a device (10, 11) for protecting the onboard electrical network against overvoltages, the two devices together controlling an excitation of an alternator supplying the onboard electrical network. According to the invention, the protection device is separate from the regulating device. An overvoltage signal (OVD) generated by the protection device (11) and controlling the excitation has priority over an excitation signal (EXC) generated by the regulating device. The regulating device and the protection device can be in the form of two separate electronic blocks on separate substrates.
