SYSTEM FOR CONTROLLING A SUPPLY VOLTAGE OF AN ON-BOARD ELECTRICAL NETWORK OF A MOTOR VEHICLE

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 exc...

Summary: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.
