The present invention is an apparatus for providing an uninterruptible power supply for an electronic device. The apparatus includes an AC-to-DC power supply that receives an external AC voltage supply and outputs a DC voltage to the electronic device. The power supply includes a bridge rectifier that rectifies the AC voltage from the external AC voltage supply, a boost power factor correction (PFC) converter that boosts the rectified voltage, and a line isolated DC-to-DC converter that changes the boosted voltage to the operating voltage range of the electronic device. The apparatus also includes an uninterruptible power supply (UPS) subsystem that contains, a controller that monitors the external AC voltage supply for interruptions, and a high voltage isolated DC-to-DC (HVDC) converter that supplies high voltage DC power directly to the PFC converter if the controller detects an interruption in the external AC voltage supply.

L'invention a trait à un appareil destiné à doter un dispositif électronique d'un système d'alimentation sans coupure. Cet appareil comprend une alimentation CA-CC qui reçoit une alimentation en tension alternative externe et émet une tension continue vers le dispositif électronique. Le bloc d'alimentation comprend un redresseur en pont qui redresse la tension alternative provenant de l'alimentation en tension alternative externe, un convertisseur de correction de facteur de puissance (PFC) amplifié qui amplifie la tension redressée, et un convertisseur de courant continu à ligne isolée qui change la tension amplifiée pour qu'elle entre dans la plage de tension de fonctionnement du dispositif électronique. L'appareil comprend également un sous-système d'alimentation sans coupure (UPS) qui comporte un régulateur surveillant les coupures de l'alimentation en tension alternative externe et un convertisseur de courant continu isolé à haute tension (HVDC) qui fournit un courant continu à haute tension directement au convertisseur PFC si le régulateur détecte une coupure de l'alimentation en tension alternative externe.
