Abstract

Una forma de onda de voltaje de correccion de convergencia (15) se aplica a un circuito amplificador de energía (100). Una etapa de salida del amplificador de energía controla una bobina de desviacion (L1) de un tubo de rayos catodicos con una corriente de correccion de convergencia (ICORR), que es proporcional a la forma de onda de voltaje de correccion de convergencia. Un potencial de voltaje diferencial (VDIFF.Q24 o VDIFF.Q26) a través de un dispositivo de salida (Q8, Q24 o Q10, Q26) de la etapa de salida se compara contra un potencial de voltaje de referencia previamente determinado (VREEF). Conforme el potencial de voltaje diferencial comienza a caer por debajo del voltaje de referencia previamente determinado, se conecta un regulador de voltaje de topología de oposicion (60, 61), que está acoplado al dispositivo de salida. El potencial de voltaje diferencial se mantiene de esta forma a un nivel mayor que el voltaje de referencia previamente determinado.
