Abstract

EL DISPOSITIVO DE DETECCION CONSTA DE UN COMPARADOR (6) QUE SUMINISTRA UNA SEÑAL REPRESENTATIVA DEL ESTADO DE CORTOCIRCUITO DE LA CARGA (2) CUANDO EL VOLTAJE DE LOS TERMINALES DE DICHA CARGA, TRAS EL FILTRADO, SE ENCUENTRA POR DEBAJO DE UN VOLTAJE DE REFERENCIA VREF. EL DISPOSITIVO CONSTA DE UNOS ELEMENTOS (7,8) PARA PRECARGAR RAPIDAMENTE EL CAPACITOR (C) DEL FILTRO (3),CUANDO LA CARGA ESTA CONECTADA. EL INTERVALO DE TIEMPO INICIAL DURANTE EL CUAL LA SEÑAL DE SALIDA DEL COMPARADOR NO ES REPRESENTATIVA DE LA PRESENCIA O AUSENCIA DE UN CORTOCIRCUITO SE REDUCE DE ESTE MODO. APLICACION EN EL CONTROL DE ACTUADORES DE LOS SISTEMAS ELECTRONICOS DE VEHICULOS DE MOTOR.
