An automotive electric system including a loop-type voltage regulating device and a method of loop regulating a voltage of an automotive electric system

摘要

The invention relates to a loop-type voltage regulating device (10), particularly for regulating a voltage of an automotive electric system, being of a type which includes at least one thermal engine (15), a voltage regulator (13) and an alternator (11) operative to deliver a system regulated-voltage signal (A+) to and receive a regulation signal (DF) from the voltage regulator (13). Advantageously, according to the invention, the voltage regulating device further includes a control unit (14) within the regulating loop, which unit is connected between the thermal engine (15) and the voltage regulator (13) and is adapted to supply the latter with a signal related to the engine operation. <IMAGE>
