Abstract

UN DISPOSITIVO CONTADOR DE ELECTRICIDAD INCLUYE AL MENOS UN CONVERTIDOR SIGMA-DELTA (20) ADAPTADO PARA EXTRAER UNA SERIE DE IMPULSOS DIGITALES, UNOS ELEMENTOS CONTADORES DIGITALES (21) PARA SUMAR LA SALIDA DEL CONVERTIDOR SIGMA-DELTA Y UNOS ELEMENTOS SEÑALIZADORES (32) PARA DISTRIBUIR UNA SEÑAL DE SALIDA (38) CUANDO LA SUMA ALCANZA UN VALOR PREDETERMINADO, CARACTERIZADO PORQUE EL DISPOSITIVO CONTADOR COMPRENDE ADEMAS UNOS ELEMENTOS (32,33) PARA AJUSTAR DIGITALMENTE LA GANANCIA DEL CONVERTIDOR E INCLUYE UNOS ELEMENTOS DE MEMORIA DIGITAL PROGRAMABLE (33) ADAPTADOS PARA ALMACENAR UN PARAMETRO QUE REPRESENTA LA GANANCIA DEL DISPOSITIVO. EL VALOR DEL PARAMETRO SE PROGRAMA EXTERNAMENTE Y UNOS ELEMENTOS DIGITALES LOGICOS (32) QUE COMBINAN LOGICAMENTE EL PARAMETRO DE GANANCIA CON LA SUMA DIGITAL ALMACENADA EN LOS ELEMENTOS CONTADORES DETERMINAN EL NUMERO DE IMPULSOS REQUERIDOS ANTES DE QUE SE ALCANCE EL VALOR DETERMINADO Y SE DISTRIBUYA UN IMPULSO DE SALIDA.
