Abstract

Un circuito de control de entrada con una corriente e salida positiva y una negativa en etapas de salida de potencia configuradas en push-pull, especialmente para su utilización en circuitos de deflexión vertical de receptores de televisión, caracterizado porque la salida del circuito de control de entrada (circuito de deflexión vertical) se conecta directamente a la base de un transistor (7) de la etapa de salida de potencia en push-pull (6, 7) porque entre3 los terminales de base de los transistores (6, 7) de la etapa de salida de potencia en push-pull, se conectan en serie dos diodos (3, 4) y, en paralelo con ellos, un condensador de carga (16), y porque se aplica una resistencia (2) a la fuente de la tensión de alimentación (UB) en la conexión entre el condensador de carga (16) y el diodo (3).
