Abstract

Un dispositivo de supresión de corriente de pista incluye una entrada acoplada entre los rieles de una vía ferroviaria y configurada para recibir un voltaje de entrada correspondiente a la corriente de pista. El dispositivo también incluye un amplificador configurado para recibir un voltaje de entrada y generar una corriente de cancelación. El dispositivo también incluye una salida acoplada entre los rieles de una vía ferroviaria y configurada para entregar la corriente de cancelación a los rieles con una polaridad invertida comparada con la corriente de pista.
