Abstract

Un circuto de desviacion horizontal incluye una primera capacitancia de retorno (C1) y una segunda capacitancia de retorno (C2). Se acopla una bobina de desviacion horizontal (Ly) a las primera y segunda capacitancias de retorno, para formar un circuito resonante, durante el retorno. Un primer transistor de conmutacion (Q1 que responde a una primer senal (CONTROLADOR HOR.) en una frecuencia de desviacion horizontal (fH) seleccionada a partir de un rango de frecuencias de desviacion horizontal, y acoplado a la primera capacitancia de retorno, genera un primer voltaje de impulso de retorno (V1) en la primera capacitancia de retorno. Un segundo transistor de conmutacion (Q2) que responde a una segunda senal de control (SALIDA DE Q8) se acopla con la segunda capacitancia de retorno. Se genera un segundo voltaje de impulso de retorno (V2) en la segunda capacitancia de retorno. El segundo voltaje de impulso de retorno se combina con el primer voltaje de impulso de retorno para producir una corriente de desviacion (iy) en la bobina de desviacion. Un cambiador de fase controlable (58) que responde a una senal de retroalimentacion (iQ4) que indica una magnitud de una corriente de suministro (Is) genera la segunda senal de control en una fase controlable con respecto a la primera senal de control, para regular la amplitud de la corriente de desviacion en cada una de las frecuencias seleccionadas mediante la transformacion de la capacitancia de retorno.
