Abstract (en)
[origin: WO2016097531A1] The method of control according to the invention slaves a DC voltage (B + A) generated by the alternator to a predetermined setpoint value by controlling an excitation current (lD) flowing in an excitation circuit (3, 6) comprising an excitation winding (6) of a rotor of the alternator. The excitation current (lD) is controlled by means of a semiconductor switch (3) controlled by a control signal (VGS) having a predetermined period. The method is of the type of those comprising a detection of a failure of the excitation circuit. In accordance with the invention, at least one short-circuit of the excitation winding is detected (Th_HEXCCD). According to another characteristic of the method, the control signal is generated on the basis of a combination (EXC_DR) of a setpoint signal (EXC) formed by pulses of the predetermined period exhibiting a duty ratio representative of the setpoint value and of a detection signal (Th_HEXCCD) indicative of the short-circuit.
