Abstract
PROCEDIMIENTO PARA EL CONTROL DEL CORTOCIRCUITO DE UN CONVERTIDOR DE CIRCUITO INTERMEDIO DE TENSION. DEBIDO A ERRORES DE INSTALACION, SE PUEDEN PRODUCIR CORTOCIRCUITOS EN UN CONVERTIDOR DE CIRCUITO INTERMEDIO O EN UNA CARGA CONECTADA A EL. SI, EN EL FUNCIONAMIENTO NORMAL, LA TENSION DEL CIRCUITO INTERMDIO SE TRANSCONECTA AL CORTOCIRCUITO MEDIANTE FRECUENCIA DE RELOJ DE LOS CONMUTADORES DEL CONVERTIDOR, PUEDEN FLUIR CORRIENTES QUE PUEDEN DESTRUIR SOBRE TODO LOS CONMUTADORES DEL CONVERTIDOR. POR TANTO, LA TENSION DEL CIRCUITO INTERMEDIO SE REDUCE A UN VALOR BAJO Y DESPUES DE UN PROGRAMA DE PRUEBA SE ACTIVA UNA SECUENCIA DE COMBINACIONES DE CONMUTADORES. EN CADA ACTIVACION DE CONMUTADOR, SE CONTROLA SI APARECE UNA SOBRECORRIENTE. DE LAS SEÑALES DE AVISO RESPECTIVAS SE PUEDEN DEDUCIR ERRORES DE INSTALACION, SIN QUE EXISTA YA EL PELIGRO DE DESTRUCCION POR SOBRECARGA DEL CIRCUITO.
