Abstract
DISPOSITIVO PARA EL AJUSTE DEL PUNTO CERO DE FUENTES DE SEN/ALES.INCLUYE UN CIRCUITO DE REGULACION (11, 13) DE LA SEN/AL DE SALIDA (10) PARA EL AJUSTE AUTOMATICO DEL PUNTO CERO A UN VALOR (W). LA SEN/AL CORRECTORA (K) GENERADA EN EL CIRCUITO REGULADOR SE ENVIA, JUNTO CON LA SEN/AL DE SALIDA DE LA FUENTE, A UN NIVEL DE ADICION DE CORRECCION (11). PARA EL RECONOCIMIENTO DE LA SITUACION DE PUNTO CERO, SE COMPARA LA SEN/AL DE SALIDA (A) CON EL VALOR AJUSTABLE (W) Y, CUANDO SE VERIFIQUE UN DESCENSO POR DEBAJO DEL MISMO, SE CONECTA ACTIVAMENTE EL CIRCUITO REGULADOR.
