Abstract

UN MONTAJE QUE ESTA PROYECTADO PARA SER CONECTADO EN SERIE EN UNA LINEA DE UN CIRCUITO ELECTRICO PARA PROTEGERLO DE UNA SOBRECARGA, COMPRENDE UN TRANSISTOR DE EFECTO DE CAMPO FET (1) A MODO DE BARRERA QUE INTERRUMPE LA CORRIENTE DE LINEA, Y UN DISPOSITIVO DE CONTROL (40) QUE ESTA CONECTADO A TRAVES DE UNA RESISTENCIA EN LA LINEA, PREFERIBLEMENTE LA RESISTENCIA DE CANAL DEL FET (1) Y POLARIZA LA PUERTA DEL FET (1) EN RESPUESTA A LA DIFERENCIA DE VOLTAJE QUE ATRAVIESA LA RESISTENCIA INTERRUMPIENDO EL FET CUANDO EL MONTAJE ESTA SUJETO A UNA SOBRECARGA EN LA LINEA. EL MONTAJE TIENE LA VENTAJA QUE DESDE QUE EL FET (1) ESTA NORMALMENTE ENCENDIDO NO HAY UNA CAIDA DE TENSION INICIAL QUE ATRAVIESE EL MONTAJE ANTES DE QUE SE VUELVA CONDUCTOR, PARA QUE EL MONTAJE PUEDA SER SUBSTANCIALMENTE LINEAL.
