Abstract

La bande d'alimentation connue (200) ou alimentation électrique ininterrompue (système UPS) couramment utilisée pour des systèmes d'ordinateurs personnels (218) sont équipées d'une alimentation CA à CC interne et une pluralité de prises de courant continu (202, 205, 208, 211) à sa surface. Les prises CC (202, 205, 208, 211) sont connectées à une sortie (CC) de l'alimentation en énergie, via un réseau de résistances, afin d'alimenter différents niveaux CC aux prises et les prises présentent des configurations différentes pour s'accoupler aux fiches à configuration donnée adaptées au niveau de tension CC approprié. L'alimentation en énergie présente un câble d'entrée avec une fiche de connexion à une prise murale et comporte des prises CA (220, 221) électriquement connectées à ce câble relié électriquement en parallèle au réseau de résistances en vue de fournir du courant CA aux prises (CA) (220, 221) à la surface de la bande. Dans un autre mode de réalisation, le système UPS est équipé de circuits de connexion entre le côté CC du convertisseur CA/CC qui s'y trouve et une pluralité de prises à la surface (202, 205, 208, 211) du système UPS afin d'y fournir une tension CC. Le système UPS est également muni de deux batteries. Une batterie est reliée entre le côté CC du convertisseur CA/CC et le côté CC du convertisseur CC/CA les deux étant de type standard dans les systèmes UPS existants. L'autre batterie est connectée entre le côté CC du convertisseur CA/CC et le circuit de détermination de la tension CC.. La première batterie constitue une réserve pour les prises CA (220, 221) dans la surface du système UPS ; la deuxième batterie constitue une réserve pour les prises CC (202, 205, 208, 211) en cas de panne de courant. L'invention concerne également un mode de réalisation à batterie unique.
