Abstract

UN SENSOR PARA MEDIDA DE GRANDES MAGNITUDES DE CORRIENTE ALTERNA (LIN) UTILIZA UN DIVISOR DE CORRIENTE (10) QUE TIENE CONDUCTORES PARALELOS (12,R1;14,R2) Y UN COMPARADOR DE CORRIENTE (16,18,20,22,24) ACOPLADO A UNO (14) DE LOS CONDUCTORES ASI DISPUESTOS DE FORMA QUE LLEVE A CABO LAS ETAPAS PRIMERA Y SEGUNDA RESPECTIVAMENTE DE ESCALADA DE LA CORRIENTE ALTERNA PARA OBTENER UNA SEÑAL DE SALIDA (LOUT) DEL SENSOR PROPORCIONAL A LA CORRIENTE ALTERNA. LA RELACION TOTAL DEL SENSOR ES EL PRODUCTO DE LAS RELACIONES DE LAS ETAPAS PRIMERA (10) Y SEGUNDA (16), PERMITIENDO ASI LA OBTENCION DE RELACIONES MUY GRANDES. LOS COMPONENTES DEL SENSOR ESTAN DISPUESTOS DE FORMA QUE SE PRODUZCA LA ANULACION DE LOS CAMPOS MAGNETICOS POR EL SENSOR Y HACER AL SENSOR INMUNE A LOS CAMPOS MAGNETICOS INCIDENTES.
