Abstract

SE PROPONE UN PROCEDIMIENTO PARA EL CONTROL DE VALVULAS RECTIFICADORAS DE UN CIRCUITO OSCILANTE PARALELO DE UN CONVERTIDOR BAJO CARGA, ALIMENTADO POR UNA FUENTE DE CORRIENTE CONTINUA, DE UN HORNO DE INDUCCION, QUE POSIBILITA UN CONTROL SIN ESCALONES O REGULACION DE LA POTENCIA CEDIDA AL HORNO DE INDUCCION, EN EL QUE POR EL ENCENDIDO DE DOS RESPECTIVAS VALVULAS RECTIFICADORAS DEL CONVERTIDOR, DIAGONALMENTE OPUESTAS, SE AJUSTA LA INTENSIDAD DE LA FUENTE DE ALIMENTACION A TRAVES DEL CIRCUITO OSCILANTE PARALELO. SON PUESTAS EN MARCHA DOS RESPECTIVAS VALVULAS RECTIFICADORAS, DIAGONALMENTE OPUESTAS (A11,A12 O B11,B12) DE FORMA TEMPORIZADA, DE FORMA QUE SE PRESENTA TEMPORALMENTE UN "CORTOCIRCUITO" DESDE EL POLO POSITIVO (1) DE LA FUENTE DE ALIMENTACION, A TRAVES DE DOS VALVULAS RECTIFICADORAS (A11,B12 O B11,A12), CONECTADAS DIRECTAMENTE EN SERIE, AL POLO NEGATIVO (2) DE LA FUENTE DE ALIMENTACION.
