Abstract

SE PROPONE UN PROCEDIMIENTO PARA EL CONTROL DE VALVULAS RECTIFICADORAS DE CORRIENTE DE DOS O MAS CIRCUITOS OSCILANTES PARALELOS DE CONVERTIDORES BAJO CARGA, CONECTADOS EN SERIE, ALIMENTADOS POR UNA FUENTE DE CORRIENTE CONTINUA COMUN, CON AL MENOS UN HORNO DE INDUCCION RESPECTIVAMENTE, QUE POSIBILITA UN AJUSTE SIN ESCALONES O REGULACION DE LA POTENCIA CEDIDA A LOS HORNOS DE INDUCCION, EN EL QUE POR EL ENCENDIDO RESPECTIVO DE LAS VALVULAS RECTIFICADORAS DE CORRIENTE DE UN CONVERTIDOR, OPUESTAS DIAGONALMENTE, ES AJUSTADA UNA INTENSIDAD DE LA FUENTE DE ALIMENTACION, A TRAVES DEL CIRCUITO PARALELO CONECTADO A ESTE CONVERTIDOR. SON PUESTAS EN MARCHA RESPECTIVAMENTE DOS VALVULAS RECTIFICADORAS (A11,A12 O B11,B12 O A21,A22 O B21,B22) DE UN CONVERTIDOR, DIAGONALMENTE OPUESTAS DE FORMA TEMPORIZADA, DE FORMA QUE SE PRESENTA TEMPORALMENTE UN "CORTOCIRCUITO", A TRAVES DE DOS VALVULAS RECTIFICADORAS DE CORRIENTE (A11,B12 O B11,A12 O A21,A22 O B21,B22) DE ESTE CONVERTIDOR, QUE ESTAN CONECTADOS DIRECTAMENTE EN SERIE.
