Abstract

SE PRESENTA UNA COLOCACION DE CONEXION PARA PROTECCION DE APARATOS ELECTRONICOS, QUE SE ALIMENTAN DE UNA FUENTE DE TENSION CONTINUA Y EN QUE SE ENCIERRE UNA CONDUCCION DE CIERRE (ASL) ESTE PREVISTO UN MOSFET (TI) COMO ELEMENTO LIMITADOR DE CORRIENTE EL MOSFET (TI) SE DESCONECTA EN INTERVALOS PERIODICOS MEDIANTE UN GENERADOR DE TENSION BASCULANTE (K) Y SE CONECTA DE NUEVO SI SE ENCUENTRA EN SU ESTADO LIMITE DE CORRIENTE. EN EL FUNCIONAMIENTO NORMAL DE LA COLOCACION DE CONEXION NO TRABAJA EL GENERADOR DE TENSION BASCULANTE (K). POR DIMENSIONAMIENTO CORRECTO DEL MISMO SE PUEDE AJUSTAR EL TIEMPO EN QUE SE BLOQUEA EL MOSFET (TI) EN RELACION CON EL TIEMPO EN QUE ACTUA UN LIMITADOR DE CORRIENTE. CON ELLO SE EVITA UN CALENTAMIENTO DEMASIADO ELEVADO DEL MOSFET (TI).
