Abstract
CIRCUITO DE PROTECCION DE TRANSISTORES EN ALIMENTADORES DE CORRIENTE CONSTANTE, QUE EVITA EL CALENTAMIENTO DE LOS TRANSISTORES EN LOS ALIMENTADORES DE CORRIENTE CONSTANTE, UTILIZADOS POR EJEMPLO EN DEPURADORES DE AGUA POR IONIZACION. EL CIRCUITO COMPRENDE UNA RESISTENCIA NTC COLOCADA EN INTIMO CONTACTO TERMICO CON LA CAPSULA DE AL MENOS UN TRANSISTOR CONECTADO COMO GENERADOR DE CORRIENTE, PARA CONTROLAR LA CORRIENTE DEL COLECTOR DEL TRANSISTOR. SE CONECTA LA RESISTENCIA ENTRE LA BASE Y EL TERMINAL DE LA FUENTE DE ALIMENTACION MAS PROXIMO ELECTRICAMENTE AL EMISOR DEL TRANSISTOR, O BIEN POR LA CONEXION DE ESTA NTC A TRAVES DE UN SEGUNDO TRANSISTOR QUE ACTUA SOBRE EL PRIMERO, DE MODO QUE AL AUMENTAR LA TEMPERATURA DEL TRANSISTOR, SU CAPSULA O EL VISITADOR A ELLA UNIDA, SE PRODUCE EL CAMBIO DE POLARIZACION DEL TRANSISTOR.
