Abstract

LA INVENCION SE REFIERE A UN CIRCUITO ELECTRICO PARA DETECTAR LA CORRIENTE DE CARGA DE UNA CARGA CONTROLADA POR RELOJ, QUE TIENE AL MENOS UN COMPONENTE INDUCTIVO ASOCIADO A UN CIRCUITO DE RUEDA LIBRE. EL CIRCUITO COMPRENDE UNA RESISTENCIA DE DERIVACION, CUYA CAIDA DE TENSION SE TIENE EN CUENTA A FIN DE DETECTAR LA CORRIENTE. SEGUN LA INVENCION, LA RESISTENCIA DE DERIVACION (S H ) ESTA SITUADA EN EL CIRCUITO DE RUEDA LIBRE (4) CON EL FIN DE DETECTAR LA CORRIENTE DE RUEDA LIBRE (I F ) QUE SE TOMA COMO MEDIDA PARA DETERMINAR LA CORRIENTE DE CARGA (CORRIENTE DEL MOTOR I M ). EN OTRA REALIZACION, LA DE RIVACION VA CONECTADA EN SERIE CON LA CARGA Y EL CIRCUITO DE RUEDA LIBRE SE ENCUENTRA EN PARALELO A LA CONEXION EN SERIE DE LA CARGA Y LA DERIVACION.
