Abstract

Un appareil utilisant un matériau intelligent stimulé électriquement nécessite une source électrique pour stimuler ledit matériau. Cette source électrique possède trois fonctions principales : (1) appliquer un potentiel de tension connu au matériau intelligent, (2) convertir la tension de commande à un niveau acceptable pour le matériau intelligent et (3) réguler la tension d'après une entrée de commande. La source électrique est un convertisseur CC/CC possédant des propriétés spéciales par l'intermédiaire de la fourniture d'une tension de stimulation variable ou de la décharge active de l'actionneur. Le circuit comprend également une zone morte, ou hystérésis, entre le point de charge et le point de décharge. Selon l'invention, l'utilisation de ce circuit avec un actionneur de matériau intelligent proportionnel à amplification mécanique permet d'obtenir un actionneur industriel à usage général constituant une solution rentable.
