Power supply system having a buffered interme- diate voltage which is supplied by an auxiliary voltage source in the event of failure of a principal voltage source, there being generated from the intermediate voltage by comparison with a threshold value a digital failure signal which both controls the auxiliary voltage source and is used to form a final failure signal.
L'invention concerne un système d'alimentation en tension comportant une tension intermédiaire (Uz) fonctionnant en tampon qui est alimentée par une source de tension auxiliaire (S2), en cas de panne de la source de tension principale (S1). Un signal de défaillance (ACF) numérique est produit à partir de la tension intermédiaire (Uz) par comparaison avec une valeur-seuil et sert à assurer la commande de la source de tension auxiliaire (S2) de même qu'à permettre de former un signal de défaillance (ACF') final.
