    • The device (1, 2) according to the invention concerns a regulator comprising a circuit (1) generating an activation command (KEY_ON) for activating the regulator by bringing, to a first voltage higher than a high reference voltage, a bidirectional line (6) connected to a detection circuit for detecting a status of the activation command. The detection circuit comprises generation means (7, 9) for generating a fault signal from a flag (LAMP_ON) indicating a failure of the alternator, linking the line to a ground by means of a switching element (7), thus bringing the line (6) to a second voltage lower than a fault voltage lower than the high reference voltage, and the control circuit (1) comprises detection means (4) for detecting the fault signal. According to the invention, 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.
    • 根据本发明的设备(1,2)涉及一种调节器,包括产生激活命令(KEY_ON)的电路(1),用于通过将高于高参考电压的第一电压引入双向线(6 )连接到用于检测激活命令的状态的检测电路。 检测电路包括用于从指示交流发电机故障的标志(LAMP_ON)产生故障信号的发生装置(7,9),通过开关元件(7)将该线路接地,从而使线路( 6)变为比低于高参考电压的故障电压低的第二电压,并且控制电路(1)包括用于检测故障信号的检测装置(4)。 根据本发明,控制电路进一步传送具有高于高参考电压的最大值和低于比故障电压高的低参考电压的最小值的设定点PWM信号,该设定点信号的占空比表示设定点 电压(V0)的调节器。
