摘要： The invention relates to a device for controlling an alternator of the type that controls a DC voltage (B+A) generated by the alternator (11) according to a predetermined set voltage (U0) by monitoring the intensity of an energizing current (IEXC) flowing through an energizing circuit of the alternator. According to the invention, the device includes a voltage-control loop (7) and a temperature-control loop (17) which comprises a temperature sensor supplying a current temperature (T) of components of the alternator, a subtracter (19) supplying a temperature error (ϵt) between the current temperature (T) and a maximum acceptable temperature (Tmax) and a control module (20) supplying a maximum admissible energizing percentage (rmax) in accordance with the temperature error according to a predetermined control law.
