Abstract
Dispositivo de rayos X que comprende un transformador regulador para controlar la tensión del tubo y diseñado para obtener una corriente del tubo que es independiente de la tensión del tubo, caracterizado por el hecho de que el regulador de la tensión del tubo está acoplado al miembro regulador de un resistor variable incluido en el circuito de alimentación del tubo de rayos X, proveyendo dicho resistor, en una posición extrema del regulador un valor tal que la caida de tensión total, que resulta de la carga sobre el tubo de rayos X, sea igual a la que ocurre cuando el regulador se encuentra en su posición extrema opuesta.
