Abstract

SE DESCRIBE UN METODO PARA CONTROLAR LA VELOCIDAD DE UNA MAQUINA DE CA (12). LA MAQUINA DE CA (12) RECIBE TRES FASES DE SALIDA (A, B, C) ALIMENTADAS DESDE UNA CICLOCONVERTIDOR (10) QUE ESTA CONECTADO A UNA ALIMENTACION DE ENTRADA (R, Y, B) DE FRECUENCIA F SUB 1. AL CICLOCONVERTIDOR (10) SE LE HACE FUNCIONAR EN TRES MODOS BAJO EL CONTROL DE UN MICROPROCESADOR (25). EL PRIMER MODO ALIMENTA A LA MAQUINA DE CA (12) EN LA GAMA DE FRECUENCIAS DE 0 A F SUB 0, MEDIANTE UNA CICLOCONVERSION CONVENCIONAL PARA GENERAR UN CONTINUO PROXIMO DE FRECUENCIAS. EL SEGUNDO MODO ACTIVA EL CICLOCONVERTIDOR (10) PARA SINTETIZAR UNA SERIE DE PASOS DE FRECUENCIAS EN LA GAMA DE FRECUENCIAS DE F SUB 0 A F SUB 1 DESDE LA ALIMENTACION DE ENTRADA (R, Y, B) Y PROPORCIONA UN CONTROL DE LA VELOCIDAD DE LA MAQUINA DE CA (12) MEDIANTE UN CONTROL DE FASE DE LA TENSION DE SALIDA (A, B, C) ENTRE CADA PASO DE FRECUENCIA. EL TERCER MODO ACTIVA EL CICLOCONVERTIDOR (10) PARA QUE SEA TRANSPARENTE, DE TAL MODO QUE LA FRECUENCIA DE ENTRADA F SUB 1 SEA ALIMENTADA DIRECTAMENTE DE MANERA EFECTIVA EN LA MAQUINA DE CA (12) SIN QUE SE APLIQUE UNA REGULACION DE LA VELOCIDAD.
