Title (EN) REDUCING POWER CONSUMPTION ON DEVICES WITH MULTIPLE POWER SUPPLIES
(FR) RÉDUCTION DE LA CONSOMMATION D'ÉNERGIE SUR LES APPAREILS DOTÉS DE PLUSIEURS ALIMENTATIONS ÉLECTRIQUES
Abstract:
(EN) A load module determines that a load of an electronic device is operating at a power level below a predetermined power threshold. The electronic device is configured to receive power simultaneously from two or more redundant power supplies. Each redundant power supply configured to receive input power from one or more power sources and configured to provide regulated output power to the load of the electronic device. A disconnection module disconnects at least one of the two or more redundant power supplies from the one or more power sources in response to the load module determining that the load of the electronic device is operating at a power level below the predetermined power threshold.
(FR) L'invention concerne un module de charge déterminant qu'une charge d'un appareil électronique fonctionne à un niveau de puissance inférieur à un seuil de puissance prédéterminé. L'appareil électronique est configuré pour recevoir l'énergie simultanément depuis deux alimentations électriques redondantes ou plus. Chaque alimentation électrique redondante est configurée pour recevoir une entrée d'énergie depuis une ou plusieurs sources d'énergie et configurée pour fournir une sortie d'énergie régulée à la charge de l'appareil électronique. Un module de déconnexion déconnecte au moins l'une des deux alimentations électriques redondantes ou plus de l'une ou des plusieurs sources d'énergie, en réponse à la détermination par le module de charge que la charge de l'appareil électronique fonctionne à un niveau de puissance inférieur au seuil de puissance prédéterminé.
