Abstract

Filtro de RFI/EMI para un sistema de accionamiento de motores de frecuencia variable, que incluye un variador de frecuencia (12) y un motor (14), comprendiendo el filtro: una bobina de choque de modo común (38); una pluralidad de elementos conductores de alimentación (26, 28, 30) que interconectan dicho motor con dicho variador de frecuencia y que pasan a través de dicha bobina de choque; un apantallamiento de tierra (40); un conductor de retorno de modo común (90) que comprende una pluralidad de elementos conductores de retorno (90a, 90b, 90c), estando cada uno de ellos interconectado entre dicho variador de frecuencia y dicho motor y dispuesto dentro de dicho apantallamiento y pasando a través de dicha bobina de choque para devolver una parte de la corriente de modo común con el fin de anular una parte de la corriente de saturación que experimenta dicha bobina de choque para aumentar la parte de la corriente de modo común transportada por dicho conductor de retorno y disminuir la parte transportada por dicho apantallamiento para reducir la RFI/EMI a la que contribuye dicho apantallamiento; y comprendiendo dicho apantallamiento de tierra (40) una pluralidad de dispositivos de apantallamiento (40a, 40b, 40c, 40d), rodeando cada uno de entre la pluralidad de dispositivos de apantallamiento un elemento correspondiente de dichos elementos conductores de alimentación (26, 28, 30) y dichos elementos conductores de retorno (90a, 90b, 90c), estando conectado cada uno de entre dichos dispositivos de apantallamiento (40a, 40b, 40c, 40d) a dicha tierra del motor y a dicha tierra del variador de frecuencia.
