Abstract

a. Circuit de commande d'impulsions à thyristors comprenant un thyristor principal et un circuit de commutation comprenant un condensateur de commutation, un contacteur de dérivation étant connecté sur le thyristor principal. b. Ils comprennent des moyens destinés à appliquer un signal de déclenchement au thyristor principal immédiatement avant l'ouverture des contacts du contacteur de dérivation et également immédiatement avant la fermeture des contacts du contracteur de dérivation pour empêcher la formation d'un arc électrique au niveau des contacts. L'application du signal de déclenchement ne se fait pas si une comparaison de la tension sur le condensateur de commutation avec le courant de charge circulant immédiatement avant la fermeture du contacteur de dérivation indique que le courant de charge est trop important pour être commuté sans problème par le condensateur de commutation sous la tension mesurée. c. Application : pour la commande du moteur d'un chariot élévateur par exemple.
