Abstract

a. Circuit de déflection horizontale pour téléviseur comportant un étage d'entraînement commutant directement un transistor de sortie, la base du transistor de sortie recevant pendant sa phase de blocage une tension élevée, opposée à la tension rendant ce transistor conducteur. b. Circuit caractérisé en ce que pendant la phase de blocage du transistor de sortie T2 l'étage d'entraînement 1 est séparé du transistor de sortie T2 par un circuit de protection 2 mis en oeuvre par l'étage d'entraînement 1.
