Abstract

La présente invention concerne un dispositif source d'alimentation qui peut fournir de manière fiable de la puissance à partir d'une source d'alimentation de réserve (seconde source d'alimentation) même lors de l'interruption d'une alimentation de puissance provenant d'une source d'alimentation principale (première source d'alimentation), et un dispositif médical faisant appel audit dispositif source d'alimentation. Le présent dispositif source d'alimentation (300) comprend une première source d'alimentation (301), un premier circuit de commande de puissance (304), une seconde source d'alimentation (311) et un second circuit de commande de puissance (314). Le second circuit de commande de puissance (314) commande la puissance fournie à une charge à partir de la seconde source d'alimentation (311) lors de l'interruption d'une puissance d'alimentation délivrée à la charge à partir de la première source d'alimentation (301). Le premier circuit de commande de puissance (304) est commandé par la puissance fournie par la seconde source d'alimentation (311).
