Abstract

La présente invention concerne une alimentation électrique de secours, comprenant : une première alimentation électrique secondaire, qui est configurée pour fournir une puissance en courant alternatif, la première alimentation électrique secondaire étant connectée à une borne d'entrée d'un convertisseur c.a./c.c. ; un convertisseur c.a./c.c., qui est configuré pour convertir une puissance en courant alternatif en une puissance en courant continu, une borne de sortie du convertisseur c.a./c.c. étant connectée à une borne de sortie de l'alimentation électrique de secours ; et une seconde alimentation électrique secondaire, qui est configurée pour fournir une puissance en courant continu, la seconde alimentation électrique secondaire étant connectée à la borne de sortie de l'alimentation électrique de secours. De plus, la présente invention concerne également un procédé de fonctionnement pour l'alimentation électrique de secours. Selon la présente invention, il est possible de fournir une solution d'alimentation électrique de secours qui est hautement fiable et qui peut s'adapter à des exigences de consommation d'énergie d'une charge ayant une grande variation d'exigences de puissance, telle qu'un ventilateur de tirage.
