More Information
Summary:The invention relates to a common-mode filter and to a device which uses said filter in order to control the doors of railway vehicles, in which the filter is intended to filter electrical noise originating from signal and power lines, essentially comprising a structure whereby the external control lines (1, 2, 3, 4) intended for common power return consist of a coil such that the sum of the input and output currents of the filter is balanced. La invención tiene por objeto un filtro en modo común y un dispositivo para el control de puertas de vehículos ferroviarios que utiliza dicho filtro, en donde el filtro tiene por objeto filtrar los ruidos eléctricos procedentes de las líneas de alimentación y de señales que básicamente se estructura de forma que las líneas de control (1, 2, 3, 4) exteriores referenciadas al retorno de alimentación común comprenden una bobina de forma que se equilibre la suma de las corrientes de entrada y salida de dicho filtro.
