Abstract
La presente invención se refiere a mejoras a un circuito de corrreción de trama para receptores de televisión, que comprende un generador de frecuencia de línea; una bobina de desviación de frecuencia de línea, acoplada al generador de frecuencia de línea; un tranformador de salida de frecuencia de línea; acoplado al generador de frecuencia de línea; caracterizadas porque comprende un suministro de energía que incluye un rectificador acoplado a un arrollamiento del transformador de salida de frecuencia de línea, para producir un voltaje de corriente contínua de la energía de régimen de línea, en el arrollamiento un generador de frecuencia de campo, acoplado al rectificador, para obtener corriente de funcionamiento del mismo, y un conductor de corriente activo acoplado en circuito con el rectificador y que responde a las señales derivadas del generador de frecuencia de campo para proporcionar una trayectoria de impedancia variable para la corriente en el rectificador, a un régimen de desviación de campo, para cargar el transformador y variar la corriente del régimen de línea en la bobina de desviación, de manera que se corrija la deformación de la trama.
