Abstract
SENSOR DE CORRIENTE Y PROCEDIMIENTO CORRESPONDIENTE UTILIZANDO REALIMENTACION GENERADA DIFERENCIALMENTE. UN SENSOR DE CORRIENTE QUE TIENE UN CANAL DE INTERFAZ DE SEÑAL CON UN TRANSFORMADOR CON UN DEVANADO PRIMARIO, OTRO SECUNDARIO Y UN DEVANADO DE REAL IMENTACION ACOPLADOS POR UN NUCLEO MAGNETICO E INCLUYE ADEMAS UN CIRCUITO GENERADOR DE REALIMENTACION QUE RESPONDE A UNA SEÑAL DE CORRIENTE ALTERNA DEL DEVANADO SECUNDARIO PARA GENERAR UNA SEÑAL DE REALIMENTACION CON UNA POLARIDAD CONTINUA. LA SEÑAL DE REALIMENTACION SIRVE PARA MANTENER SUSTANCIALMENTE EN CERO UN FLUJO EN EL NUCLEO MAGNETICO. EL CIRCUITO GENERADOR DE REALIMENTACION INCLUYE UN AMPLIFICADOR OPERACIONAL, CON UNAS PUERTAS DE ENTRADA DIFERENCIAL, Y OTRAS DE SALIDA DIFERENCIAL, Y UN CONJUNTO DE CONMUTACION QUE GENERA UNA SEÑAL DE COMPENSACION CA A PARTIR DE UNA TENSION COMPENSADORA CC QUE SE ACOPLA CONVENIENTEMENTE AL AMPLIFICADOR OPERACIONAL A TRAVES DEL NUCLEO MAGNETICO.
