Title
(EN) SYSTEMS AND METHODS FOR REDUCING POWER LOSSES IN A MEDICAL DEVICE
(FR) SYSTÈMES ET PROCÉDÉS DESTINÉS À RÉDUIRE LES PERTES DE PUISSANCE DANS UN DISPOSITIF MÉDICAL
Abstract
(EN)
A system for reducing power loss in a medical apparatus may include multiple power sources (14), a power source switch matrix (22), a diode (36), and a diode bypass switch (34). The power source switch matrix may control whether each power source is currently providing power to the power load. The diode may be electrically coupled to a first power source to prevent current from one or more of the other power sources from being applied to the first power source. The diode bypass switch may be coupled to the first power source and is operable to switch between a first state in which a current pathway from the first power source to the power load includes the diode and a second state providing a current pathway from the first power source to the power load that circumvents the diode.

L'invention concerne un système destiné à réduire la perte de puissance dans un appareil médical et pouvant comprendre de multiples sources de puissance, une matrice de commutation de source de puissance, une diode et un commutateur de dérivation pour diode. La matrice de commutation de source de puissance peut contrôler chaque source de puissance en vue de déterminer si elle fournit de la puissance à la charge de puissance. La diode peut être couplée électriquement à une première source de puissance de façon à empêcher l'application du courant provenant de l'une ou plusieurs des autres sources de puissance sur la première source de puissance. Le commutateur de dérivation pour diode peut être couplé à la première source de puissance et permet d'effectuer une commutation entre un premier état, dans lequel un passage de courant de la première source de puissance à la charge de puissance inclut la diode, et un second état, dans lequel un passage de courant de la première source de puissance à la charge de puissance contourne la diode.
