Abstract
The invention relates to a device for supplying electricity at overvoltage in an automobile. Automobile circuits comprise a main circuit (1) and an auxiliary circuit (2) requiring to be temporarily supplied at overvoltage. The main circuit is normally supplied by a battery (3) fed by an alternator (4) of which the excitation circuit is regulated by a regulator (5). In accordance with the invention, the device includes commutation means (6) controlled from the stator output of the alternator on the auxiliary load (2), the excitation of the alternator (4) following this commutation being taken via the regulator (5) to a sufficient value as a function of the state of the engine (M) for assuring a temporary supply state of the auxiliary circuits (2) at overvoltages and at reduced current. Application to supply of electric circuits of automobiles or the like.
