Abstract
The invention relates to a device for controlling an alternator of the type that controls a DC voltage (B+A) generated by the alternator () according to a predetermined set voltage (U) by monitoring the intensity of an energizing current (I) flowing through an energizing circuit of the alternator. According to the invention, the device includes a voltage-control loop () and a temperature-control loop () which comprises a temperature sensor supplying a current temperature (T) of components of the alternator, a subtracter () supplying a temperature error (ϵ) between the current temperature (T) and a maximum acceptable temperature (T) and a control module () supplying a maximum admissible energizing percentage (r) in accordance with the temperature error according to a predetermined control law.
