Abstract
Sistema para control de corriente directas, especialmente para instalaciones para carga de acumuladores, consistente en uno o más núcleos de imán, de material ferromagnético, con un enrollado de entrada que atraviesa la corriente controlada, de un enrollado de imantación que va conectado, por la entrada de voltaje alterno de un puente rectificador en acoplamiento de Graetz, con la salida de un generador de impulsos, y de un enrollado de acoplamiento de reacción que, mediante una resistencia graduable, va conectado con la salida de voltaje directo del puente Graez y rectificador caracterizado, de este modo, porque el generador de impulsos es en sí un generador de onda rectangular porque los enrollados de acoplamiento de reacción están montados de tal modo que su flujo magnético tiene el mismo sentido que el del conductor de corriente directa, y porque como indicador de voltaje se utiliza uno Schmitt-Trigger.
