Abstract
Device for supplying the inductor (3) of a rotating electrical machine, the device comprising a circuit (21) for supplying the inductor in nominal mode. The device also includes a circuit (22) for supplying the inductor (3) in auxiliary mode and a mode selector (23) capable, on the one hand, of comparing the output voltage (Ualt) delivered by the machine with a threshold voltage at least equal to the minimum voltage for operating the nominal supply circuit (21) and, on the other hand, of selecting the auxiliary supply mode if the output voltage (Ualt) is below the threshold voltage. Application to motor vehicle load circuits.
Claims7
Device for supplying the field winding (3) of a rotary electrical machine, the said device comprising a circuit (21) for supplying the said field winding in nominal mode, characterised in that the said device also comprises a circuit (22) for supplying the field winding (3) in auxiliary mode and a mode selector (23) able firstly to compare the output voltage (Ualt) delivered by the machine with a threshold voltage (Uthreshold) at least equal to the minimum operating voltage of the said nominal supply circuit (21) and secondly to select the said auxiliary supply mode if the said output voltage (Ualt) is less than the said threshold voltage (Uthreshold).
