A system for an AC electrical circuit includes an actuator (110), a source (115), and an actuator control system (120). The actuator converts current into a force to move contacts relative to one another to switch power on and off in the AC electrical circuit. The source operates to supply current to the actuator. The actuator control system is connected to the actuator and to the source to control the current to the actuator. The current to the actuator is independent of a voltage produced by the actuator during switching and a voltage at which the source operates.

La présente invention concerne un circuit électrique de courant alternatif comportant un actionneur (110), une source (115), et un système de contrôle de l'actionneur (120). L'actionneur convertit le courant en une force pour déplacer les contacts les uns par rapport aux autres pour assurer ou interrompre l'alimentation dans le circuit électrique de courant alternatif. La source fonctionne pour alimenter l'actionneur en courant. Le système de contrôle de l'actionneur est relié à l'actionneur et à la source pour contrôler le courant fourni à l'actionneur. Le courant fourni à l'actionneur est indépendant de la tension produite en cours de commutation et d'une tension à laquelle la source fonctionne.
