Abstract

Perfeccionamientos en los mandos de excitación de doble polaridad, del tipo de los que parten de una fuente de corriente continua con toma central, caracterizados por comprender un mando diferencial potenciométrico de alta impedancia cuya señal es adecuadamente amplificada antes de incidir en un bloque diferenciador destinado a desviar dicha señal hacia dos grupos amplificadores distintos, uno de ellos positivo y el otro negativo, cuyos bornes de salida están conectados en paralelo de forma que una carga conectada entre este borne común y la toma central de la fuente de corriente continua, dicha carga queda sometida a un paso de corriente cuyo valor y cuya polaridad dependen de la posición del cursor diferencial potenciométrico.
