Title
(EN) ADAPTIVE POWER SYSTEMS AND TECHNIQUES
(FR) SYSTÈMES ET TECHNIQUES D'ALIMENTATION ADAPTATIVE
Abstract
(EN) An apparatus is disclosed for adaptively providing power. In example implementations, an apparatus includes a power adapter coupler, at least one transistor, a first charger, and a second charger. The first charger and the second charger are coupled between the power adapter coupler and the transistor. The apparatus also includes a first switch, a second switch, and a charging controller. The first switch is coupled in series with the first charger between the power adapter coupler and the transistor. The second switch is coupled in series with the second charger between the power adapter coupler and the transistor. The charging controller is coupled to the first switch and the second switch. The charging controller is configured to selectively close the first switch to connect the first charger to the at least one transistor or close the second switch to connect the second charger to the at least one transistor.
(FR) Est divulgué un appareil pour fournir une alimentation de manière adaptative. Dans des modes de réalisation donnés à titre d'exemple, un appareil comprend un coupleur d'adaptateur d'alimentation, au moins un transistor, un premier chargeur et un second chargeur. Le premier chargeur et le second chargeur sont couplés entre le coupleur d'adaptateur d'alimentation et le transistor. L'appareil comprend également un premier commutateur, un second commutateur et un contrôleur de charge. Le premier commutateur est couplé en série au premier chargeur entre le coupleur d'adaptateur d'alimentation et le transistor. Le second commutateur est couplé en série au second chargeur entre le coupleur d'adaptateur d'alimentation et le transistor. Le contrôleur de charge est couplé au premier commutateur et au second commutateur. Le contrôleur de charge est configuré pour fermer sélectivement le premier commutateur pour connecter le premier chargeur au ou aux transistors, ou pour fermer le second commutateur pour connecter le second chargeur au ou aux transistors.
