摘要： The method of control according to the invention slaves a DC voltage generated by the alternator to a predetermined setpoint value by controlling an excitation current flowing in an excitation circuit comprising an excitation winding of a rotor of the alternator. The excitation current is controlled by means of a semiconductor switch, in turn controlled by a control signal having a predetermined period. The method comprises a detection of a failure of the excitation circuit. At least one short-circuit of the excitation winding is detected. According to another characteristic of the method, the control signal is generated on the basis of a combination of a setpoint signal formed by pulses of the predetermined period exhibiting a duty ratio representative of the setpoint value and of a detection signal indicative of the short-circuit.

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.
