Abstract

Dispositif pour appliquer une tension de commande aux extrémités d'un élément de positionnement piézo-électrique. Afin de pouvoir appliquer une tension élevée aux extrémités dudit élément sans devoir utiliser dans ce but une tension d'alimentation relativement élevée, la capacité dudit piézo-électrique est utilisée comme élément intégrateur. Le dispositif comporte une source de charge et des commutateurs, alors que sous la commande d'impulsions de courant, des charges en forme d'impulsion sont fournies à l'élément piézo-électrique ou évacuées de celui-ci.
