Abstract
REGULADORES DE CONMUTACIN PARA ACTIVAR CIRCUITOS DE DEFLEXION HORIZONTAL DE TELEVISION. UNA FUENTE DE ALIMENTACION (10) DE ENERGIA, A TRAVES DE UN TRANSFORMADOR (24), A UN CIRCUITO DE DEFLEXION (4). A ESTE CIRCUITO SE ACOPLA UN OSCILADOR (6). UN DEVANADO SECUNDARIO (24B) DA SEÑAL AL ULTOR DE UN CINESCOPIO, Y OTRO DEVANDAO (24C) SE ACOPLA A UN CIRCUITO GENERADOR DE TENSION DE REFERENCIA (33). UN CIRCUITO REGULADOR (20), ALIMENTADO DESDE EL PUENTE RECTIFICADOR (16), COMPRENDE EL CONMUTADOR REGULADOR BIDIRECCIONAL (26) QUE CONTROLA EL PASO DE ENERGIA AL CIRCUITO DE DEFLEXION (40) CONTROLANDO EL DEVANADO PRIMARIO (24A) DEL TRANSFORMADOR (24).
