Abstract

EL TRANSFORMADOR (9) DE UN CONMUTADOR DE BLOQUEO SE MAGNETIZA POR ABSORCION DE ENERGIA, EN LA FASE DE FLUJO CUANDO ESTA CONECTADO UN INTERRUPTOR (7) EN EL LADO PRIMARIO. EN LA FASE DE BLOQUEO, CUANDO EL INTERRUPTOR (7) ESTA DESCONECTADO, SE DESMAGNETIZA EMITIENDO ENERGIA A LA CARGA DEL LADO SECUNDARIO. EL INTERRUPTOR (7) DEBERIA SER CONECTADO DE NUEVO CUANDO EL TRANSFORMADOR (9) ESTA TOTALMENTE DESMAGNETIZADO. PARA ASEGURARLO SE PROPONE CREAR UNA TENSION DE TRANSFORMADOR (TENSION DE REACOPLAMIENTO) Y LIBERAR LA CONEXION DEL INTERRUPTOR (7) SI LA TENSION DE REACOPLAMIENTO HAYA CAMBIADO DE VALORES DE UN PRIMER SIGNO AVALORES DEFINIDOS CON EL SIGNO CONTRARIO. PARA PERMITIR UN COMIENZO DE OSCILACIONES, EL VALOR UMBRAL (23) DEBE PARTIR DE CERO, EN LA PUESTA EN MARCHA DE LA FUENTE DE ALIMENTACION, Y PERMANECER EN ESTE VALOR HASTA QUE LA TENSION EMPIECE A AUMENTAR ENCIMA DE LA CARGA. ESTE DESPLAZAMIENTO DEL VALOR DE UMBRAL SE REALIZA MEDIANTE UNA SIMPLE MODIFICACION EN LA CONEXION EXTERIOR DE LOSCOMPONENTES DE MANDO YA EXISTENTES.
