Abstract

UN SISTEMA DE ALIMENTACION DE ENERGIA ELECTRICA ININTERRUMPIBLE MEJORADO QUE INCLUYE UN TRANSFORMADOR PARA AUMENTAR O DISMINUIR EL VOLTAJE OBTENIDO DE UN INVERSOR Y EL VOLTAJE OBTENIDO DE UNA LINEA DE DERIVACION HASTA UN NIVEL PREDETERMINADO, OTRO TRANSFORMADOR PARA DISMINUIR EL VOLTAJE, Y UN TRANSFORMADOR INTEGRADO QUE TIENE UNA BOBINA DE REACTANCIA. EL PRESENTE INVENTO INCLUYE UN CONVERTIDOR PARA CONVERTIR VOLTAJE DE CORRIENTE ALTERNA EN VOLTAJE DE CORRIENTE CONTINUA; UN INVERSOR PARA MODULAR EL VOLTAJE DE CORRIENTE CONTINUA AL QUE SE DA SALIDA DESDE UNA BATERIA O DESDE EL CONVERTIDOR, UN PRIMER CONMUTADOR PARA CONMUTAR EL VOLTAJE MODULADO EN EL INVERSOR; UN SEGUNDO CONMUTADOR PARA CONMUTAR EL VOLTAJE ALTERNO AL QUE SE HA DADO ENTRADA A TRAVES DE LA LINEA DE DERIVACION; MEDIOS PARA AUMENTAR O DISMINUIR LOS VOLTAJES DE SALIDA DEL PRIMER CONMUTADOR Y DEL SEGUNDO CONMUTADOR; UN TRANSFORMADOR INTEGRADO QUE ACTUA COMO UNA BOBINA DE REACTANCIA, PARA CONFIGURAR EL VOLTAJE DE SALIDA DEL PRIMER CONMUTADOR; Y UN CONDENSADOR PARA CONFIGURAR LAS FORMAS DE ONDA DEL VOLTAJE DE SALIDA DEL TRANSFORMADOR INTEGRADO.
