Abstract

Un dispositivo de circuito de barrido de línea para receptor de televisión, que comprende: una bobina de desviación de línea, conectada en serie con un condensador de ida de barrido, un primer interruptor bidireccional, que lleva un tiristor y un diodo, montados en contraposición, estando este primer interruptor conectado en paralelo con el conjunto formado por el desviador de línea y el condensador de ide de barrido, un segundo interruptor bidireccional, que lleva un tiristor y un diodo, montados en contraposición, y mandado por una señal procedente de un circuito oscilador a la frecuencia de línea, un circuito reactivo, que lleva una primera inductancia, en serie con una red capacitiva, y que enlaza eléctricamente la unión ánodo del tiristor y cátodo del diodo del primer interruptor con la unión ánodo del tiristor y cátodo del diodo del segundo interruptor, estando la citada unión del segundo interruptor, por otra parte, conectada a una fuente de tensión continua, a través de una segundainductancia, y permitiendo este segundo interruptor, cuando se encuentra en posición cerrada, por una parte, el paso de una corriente oscilante en el primer interruptor, a fin de permitir la anulación de la corriente en el tiristor de este primer interruptor, y por otra parte, la transferencia de la energía de la fuerte hacia la bobina del barrido de línea, asociada al condensador de ida de barrido, caracterizado porque el primer interruptor es mandado en la báscula de su tiristor, por una señal elaborada a partir de la señal disponible en la unión de la primera inductancia y de la red capacitiva del circuito reactivo.
