Abstract

FUENTE DE ALIMENTACION DE ANTORCHAS DE HORNOS DE PLASMA QUE PARTIENDO DE UNA TENSION DE RED SUPERIOR A 300V. SE DISPONE DE UN TRANSFORMADOR DODECAFASICO QUE ALIMENTA DOS PUENTES DE DIODOS A CUYA SALIDA SE DISPONE DE INDUCTANCIA Y CONDENSADOR, APLICANDO SU TENSION DE SALIDA DE APROXIMADAMENTE 300V. A CUATRO ETAPAS CONVERTIDORES QUE CONSTAN DE IGBT''S E INDUCTANCIA DE SALIDA DE PEQUEÑO VALOR Y CON NUCLEO DE AIRE UN CIRCUITO DE CONTROL QUE RECIBE COMO CONSIGNA DE TRABAJO LA INTENSIDAD DE SALIDA DE LA FUENTE Y LAS INTENSIDADES DE SALIDA DE CADA IGBT''S, PROPORCIONANDO LAS SEÑALES DE ATAQUE A LOS IGBT''S PARA CONMUTARLOS EN BASE A BANDAS DE INTENSIDAD DE SALIDA PREFIJADAS Y CON UNA FRECUENCIA DE 10KHZ. DE APLICACION EN LA INDUSTRIA DEL PLASMA.
