Abstract

Un circuito de centrado de bobina de deflexion horizontal que incluye un transistor (Q453) Darlington y un diodo (D60). El transistor Darlington y el diodo forman una red no lineal que se acopla en serie con un inductor (452). E l arreglo en serie del inductor y la red no lineal se acopla en paralelo con una bobina de deflexion horizontal (LY). El voltaje de base del transistor Darlington se produce por un divisor (450, 451, 453) de voltaje acoplado en un trayecto de corriente de la corriente (i500) del inductor.
