Abstract
Circuit destiné à produire un courant en dents de scie dans une bobine. La bobine est reliée à un condensateur de retour et un condensateur d'aller du spot en formant un circuit de déviation à oscillation libre, en parallèle duquel est montée une première diode qui conduit pendant une première partie de l'intervalle d'aller du spot; ce circuit est également en parallèle au moyen d'une seconde diode conduisant pendant une seconde partie de l'intervalle d'aller avec un interrupteur commandé conduisant pendant une partie de l'intervalle d'aller et relié, par une première bobine d'induction, à une tension d'alimentation. Applications : notamment aux circuits de déviation de tubes à rayons cathodiques de télévision.
