Title (EN) POWER MANAGEMENT SYSTEM FOR BATTERY-POWERED AUDIO DEVICE
(FR) SYSTÈME DE GESTION DE COURANT DESTINÉ À UN DISPOSITIF AUDIO ALIMENTÉ PAR BATTERIE
Abstract:
(EN) Embodiments provide a power management system for a battery-powered audio device. The system includes bi-directional power conversion and control circuitry to implement a corresponding control scheme. The system may be switchable between a charge mode, during which the power conversion and control circuitry charges the battery of the audio device and the AC/DC adapter provides an amplifier supply voltage to one or more amplifiers of the audio device, and a discharge mode, in which the power conversion and control circuitry may provide a regulated amplifier supply voltage to the one or more amplifiers that is regulated based on one or more operating conditions of the system. The system may provide reduced cost and reduced power consumption and reduced size compared with prior systems.
(FR) Des modes de réalisation de la présente invention concernent un système de gestion de courant destiné à un dispositif audio alimenté par batterie. Le système comprend une circuiterie de commande et de conversion de courant bidirectionnelle permettant de mettre en œuvre un schéma de commande correspondant. Le système peut être commuté entre un mode de charge, pendant lequel la circuiterie de commande et de conversion de courant charge la batterie du dispositif audio et l'adaptateur CA/CC fournit une tension d'alimentation d'amplificateur à un ou plusieurs amplificateurs du dispositif audio, et un mode de décharge, dans lequel la circuiterie de commande et de conversion de courant peut fournir une tension d'alimentation d'amplificateur régulée auxdits amplificateurs qui est régulée sur la base d'une ou plusieurs conditions de fonctionnement du système. Le système peut garantir un coût réduit, une consommation d'énergie réduite et une taille réduite par comparaison aux systèmes antérieurs.
