Abstract

Un circuit d'attaque pour un circuit de déviation horizontale pouvant fonctionner à plusieurs fréquences de balayage horizontal comprend deux transistors (13, 14) en push-pull; les sources de tension (23, 24) des transistors du circuit d'attaque, qui produisent l'attaque directe et inverse pour le transistor de sortie horizontale, produisent des niveaux de tension qui dépendent de la fréquence de balayage horizontal choisie afin de diminuer la dissipation de puissance pendant la commutation du transistor de sortie horizontale (15).
