Abstract

MEJORAS INTRODUCIDAS EN LOS SISTEMAS DE GENERACION Y CONTROL DE CORRIENTE PARA PROCESOS ELECTROLITICOS. CONSISTEN EN UTILIZAR DOS AUTOTRANSFORMADORES (1-2), CONECTADOS EN PARALELO A UNA MISMA FASE Y DOTADOS DE RESPECTIVOS RECTIFICADORES DE MEDIA ONDA (5-6), DE MANERA QUE EL RECTIFICADOR (5) ELIMINA LAS SEMIONDAS NEGATIVAS DEL AUTOTRANSFORMADOR (1) Y EL RECTIFICADOR (6) ELIMINA LAS SEMIONDAS POSITIVAS DEL AUTOTRANSFORMADOR (2), CON LO QUE A LA ENTRADA (7) DE LA CUBA (8), SE CONSIGUE UNA TENSION ALTERNA SIMETRICA O ASIMETRICA, SEGUN LAS NECESIDADES DE CADA CASO. SUS SEMIONDAS POSITIVA Y NEGATIVA SON CONTROLABLES INDEPENDIENTEMENTE, CONCRETAMENTE A TRAVES DE UN MICROPROCESADOR (11) QUE EN FUNCION CON UN PROGRAMA ESTABLECIDO POR MEDIO DE UN ALGORITMO MATEMATICO Y CON LA TENSION QUE EN CADA MOMENTO EXISTE EN LA ENTRADA (7) DE LA CUBA, ACTUA SOBRE REGULADORES AUTOMATICOS (4) DE LOS AUTOTRANSFORMADORES (1-2) Y EN SU CASO SOBRE LOS TIRISTORES (5-6) QUE PARTICIPAN EN LOS RECTIFICADORES DE MEDIA ONDA, PARA CONTROLAR LOS ANGULOS DE CONDUCCION.
