Abstract

L'invention concerne un circuit d'attaque pour un transistor de sortie de déviation d'un tube-image couleurs, comprenant un transformateur d'attaque ayant un enroulement secondaire couplé à une jonction base-émetteur du transistor de sortie et également un enroulement primaire ; un moyen de commutation d'attaque couplé en série à l'enroulement primaire du transformateur d'attaque pour former ainsi un enroulement commuté; un premier moyen de stockage d'énergie couplé à l'enroulement commuté ; une première source de potentiel d'excitation couplée au premier moyen de stockage d'énergie ; un second moyen de stockage d'énergie et un moyen conducteur de courant unidirectionnel couplé aux premier et second moyens de stockage d'énergie pour produire entre eux un écoulement d'énergie. Selon l'invention une seconde source B2 de potentiel d'excitation est couplée au second moyen de stockage d'énergie 42, la seconde source B2 ayant une grandeur sensiblement inférieure à celle de la première source B1. L'invention s'applique notamment aux téléviseurs couleurs.
