Abstract

Circuit de génération d'un courant en dents de scie dans une bobine. Selon l'invention, un condensateur est connecté d'un côté à un transistor commutateur 19 et de l'autre côté à un circuit comprenant un deuxième inducteur et à travers une diode à un condensateur de retour. Lorsque le transistor n'est pas conducteur, l'énergie est délivrée au condensateur et lorsqu'il est conducteur le condensateur est complètement déchargé dans le deuxième inducteur. Application : en particulier dérivation de lignes pour téléviseurs.
