Abstract

Perfeccionamientos en generadores de impulsos directrices, con un indicador de valor límite al que se alimenta la tensión a controlar y en cuya salida al sobrepasarse un valor límite ajustable hay una primera señal definida y al no llegarse al valor límite hay una segunda señal definida, caracterizados porque la tensión a controlar en una parte de de abastecimiento está aplicada al circuito serio de una fuente de corriente constante y de dos condensadores, estando conectado en paralelo a cada condensador un diodo Zener, porque como indicador de valor límite está previsto un amplificador operacional cuya entrada normal está enlazada con la toma de un divisor de tensión regulable en el que se halla la tensión a controlar, y cuya entrada en oposición está enlazada con el punto de unión de ambos condensadores, y porque entre la entrada normal y la entrada en oposición de amplificador operacional está conectado un circuito serie de dos dichos cuyo punto de unión está enlazado en la toma de un elemento RC, cuya resistencia está enlazada con el punto de unión entre la fuente de corriente constante y el condensador.
