Abstract

L’invention concerne un système d’alimentation comprenant : une première (Ba1), une deuxième (Ba2) et une troisième (Ba3) borne d’alimentation distinctes les unes des autres, une borne de régulation de tension (Br), une borne de sortie (Bs) connectée électriquement à ladite borne de régulation de tension (Br),une première batterie (Bat1) générant une première tension d’alimentation (Va1) entre ladite première borne d’alimentation (Ba1) et ladite deuxième borne d’alimentation (Ba2),une deuxième batterie (Bat2) générant une deuxième tension d’alimentation (Va2) entre ladite deuxième borne d’entrée (Ba2) et ladite troisième borne d’alimentation (Ba3), ladite deuxième batterie (Bat2) étant connectée en série avec ladite première batterie (Bat1) de sorte à fournir une première tension de sortie (Vs1) entre la ladite troisième borne d’alimentation (Ba3) et ladite première borne d’alimentation (Ba1),un convertisseur de tension DC/DC (10) configuré pour dans un premier mode de fonctionnement convertir ladite première tension de sortie (Vs1) en une deuxième tension de sortie (Vs2) entre ladite borne de régulation (Br) et ladite première borne d’alimentation (Ba1), ladite deuxième tension de sortie (Vs2) étant inférieure à ladite première tension de sortie (Vs1) et configuré pour dans un deuxième mode de fonctionnement ne pas réguler la tension entre ladite borne de régulation (Br) et ladite première borne d’alimentation (Ba1),un interrupteur de connexion (Int_c) reliant ladite deuxième borne d’alimentation (Ba2) et ladite borne de sortie (Bs), et une résistance de connexion (R) connectée en parallèle dudit interrupteur de connexion (Int_c), ledit système d’alimentation étant conçu pour générer une troisième tension de sortie (Vs3) entre ladite borne de sortie (Bs) et ladite première borne d’alimentation (Ba1).
