Abstract

Mejoras en un aparato interruptor para el control de corriente en motores de tracción que funciona con una fuente de voltaje de corriente continua y que tiene una salida para controlar la excitación de una carga, caracterizadas porque comprenden: un primer rectificador controlable conectado para proveer una trayectoria para la corriente de carga entre la fuente de voltaje y la salida, control de conducción para controlar la condición conectada de funcionamiento del primer rectificador controlable, para suministrar corriente a la salida, conmutadores para controlar la condición de funcionamiento desconectado del primer rectificador controlable, el conmutador incluye un condensador y un inductor acoplados con el primer rectificador controlable, un segundo rectificador controlable conectado entre la fuente de voltaje y el condensador para proveer una carga de voltaje de una primera polaridad al condensador circuitos de carga conectados con el condensador y la fuente de voltaje para proveer unavía de corriente y mantener una carga predeterminada de voltaje de polaridad opuesta en el condensador, en relación con la fuente de voltaje.
