Abstract
(EN)
An information handling system includes a power supply and a power assist unit. The power supply powers a power rail. The power assist unit includes a power storage element, a converter including a switching device coupled to provide power from the power storage element to the power rail, and a controller configured to receive a load indication that indicates a power demanded by the load and to provide an intermediate output based upon the load indication. The controller includes a boost element to receive the intermediate output and to provide a controller output. The controller output is a sum of a bias voltage level provided by the bias element and the intermediate output. The controller output is coupled to a gate terminal of the switching device. The converter provides power from the power storage element to the power rail in response to the controller output.

La présente invention concerne un système de traitement d'informations comprenant une alimentation électrique et une unité d'assistance électrique. L'alimentation électrique alimente un rail d'alimentation. L'unité d'assistance électrique comprend un élément de stockage d'énergie, un convertisseur comprenant un dispositif de commutation couplé pour fournir de l'énergie entre l'élément de stockage d'énergie et le rail d'alimentation, et un dispositif de commande conçu pour recevoir une indication de charge qui indique une puissance demandée par la charge et pour fournir une sortie intermédiaire sur la base de l'indication de charge. Le dispositif de commande comprend un élément d'amplification pour recevoir la sortie intermédiaire et pour fournir une sortie de dispositif de commande. La sortie de dispositif de commande est une somme d'un niveau de tension de polarisation fourni par l'élément de polarisation et la sortie intermédiaire. La sortie de dispositif de commande est couplée à une borne de grille du dispositif de commutation. Le convertisseur fournit de l'énergie entre l'élément de stockage d'énergie et le rail d'alimentation en réponse à la sortie de dispositif de commande.
