Abstract

DISPOSITIVO DE PROTECCION DE UN TRANSISTOR DE POTENCIA QUE CONSTITUYE EL VARIADOR DE VELOCIDAD DE UN MOTOR ELECTRICO DE PEQUEÑA POTENCIA DE CORRIENTE CONTINUA. CONSTA DE MEDIOS SENSIBLES A UNA TENSION DE MANDO PARA HACER VARIAR LA TENSION DISPONIBLE EN LOS BORNES DEL MOTOR EN EL MISMO SENTIDO QUE LA CITADA TENSION Y PARA MENTENER LA TENSION ENTRE DOS VALORES PREESTABLECIDOS; PORQUE LOS CITADOS MEDIOS SENSIBLES COMPRENDEN UNA ETAPA DIFERENCIAL DE TRANSISTORES Y UN AMPLIFICADOR OPERACIONAL; PORQUE LA TENSION DISPONIBLE PARA EL MANDO ESTA LIMITADA POR UN DIODO ZENER; Y PORQUE LA ENTRADA DE MANDO DE LOS CITADOS MEDIOS ESTA ENLAZADA, POR UNA PARTE, A LA SALIDA DE UN POTENCIOMETRO Y, POR OTRA PARTE, A UN DIVISOR DE TENSION.
