Abstract

SE PRESENTA UN CONVERTIDOR DE ALIMENTACION QUE INCLUYE UN AMPLIFICADOR EN PUENTE ALIMENTADO POR UNA FUENTE DE ALIMENTACION UNICA O SENCILLA DE CORRIENTE CONTINUA MEDIANTE UNA PLURALIDAD DE CONVERTIDORES CONECTADOS EN PARALELO DE MODULACION DE IMPULSOS EN DURACION. LOS CONVERTIDORES ESTAN MODULADOS CON SEÑALES DE REFERENCIA QUE OPERAN EN UNA ALTERNACION DE TIEMPO DE MANERA QUE EN CUALQUIER CICLO DE CONVERSION EXISTE UNA PLURALIDAD DE ONDAS MODULATORIAS QUE SON IDENTICAS EXCEPTO POR SUS RETRASOS DE TIEMPO Y QUE SE DISTRIBUYEN EQUIESPACIADAMENTE EN EL TIEMPO DENTRO DE UN SOLO CICLO DE CONVERSION. UN AMPLIFICADOR DE REGULACION POR CONTRARREACCION COMPARA LA SALIDA DE VOLTAJE DE LOS CONVERTIDORES CONECTADOS EN PARALELO A TRAVES DE LA MAGNITUD DEL SUMINISTRO DE VOLTAGE REQUERIDO POR EL AMPLIFICADOR Y OCASIONA QUE LOS COMPONENTES MODULADORES DEL CIRCUITO CONTROLEN EL CICLO DE CONMUTACION DE CADA UNO DE LOS CONVERTIDORES DE MODULACION DE IMPULSOS EN DURACION.
