Abstract

UN CONVERTIDOR DE ALIMENTACION PWM (MODULACION DE ANCHURA DE IMPULSOS) QUE COMPRENDE UNA PRIMERA RAMIFICACION DE CONMUTACION DE UN PRIMER DISPOSITIVO DE CONMUTACION Y UNA PRIMERA INDUCTANCIA ENTRE UN TERMINAL POSITIVO DE LA FUENTE Y UN TERMINAL DE LA CARGA Y UNA SEGUNDA RAMIFICACION DE CONMUTACION DE UNA SEGUNDA INDUCTANCIA, Y UN SEGUNDO DISPOSITIVO DE CONMUTACION ENTRE EL TERMINAL DE CARGA Y UN TERMINAL NEGATIVO DE LA FUENTE. PARA REDUCIR EL RUIDO Y LAS PERDIDAS, EL CONVERTIDOR DE ALIMENTACION ESTA PROVISTO ADEMAS CON UNA COMBINACION EN SERIE DE UN TERCER Y CUARTO CONDENSADORES CONECTADOS ENTRE LOS TERMINALES POSITIVO Y NEGATIVO DE LA FUENTE, UNA COMBINACION EN SERIE DEL PRIMER DIODO Y DEL PRIMER CONDENSADOR CONECTADOS ENTRE UN PRIMER PUNTO DE UNION ENTRE EL TERCERO Y CUARTO CONDENSADORES Y UN SEGUNDO PUNTO DE UNION ENTRE EL PRIMER DISPOSITIVO DE CONMUTACION Y LA PRIMERA INDUCTANCIA, UNA COMBINACION EN SERIE DEL SEGUNDO CONDENSADOR Y EL SEGUNDO DIODO CONECTADOS ENTRE UN TERCER PUNTO DE UNION ENTRE LA SEGUNDA INDUCTANCIA Y EL SEGUNDO DISPOSITIVO DE CONMUTACION Y UN CUARTO PUNTO DE UNION ENTRE EL TERCER Y CUARTO CONDENSADORES, UNA COMBINACION EN SERIE DEL TERCER DIODO Y LA TERCERA INDUCTANCIA CONECTADOS ENTRE UN QUINTO PUNTO DE UNION ENTRE EL PRIMER DIODO Y EL PRIMER CONDENSADOR Y EL TERMINAL POSITIVO DE LA FUENTE, Y UNA COMBINACION EN SERIE DE LA CUARTA INDUCTANCIA Y EL CUARTO DIODO CONECTADOS ENTRE EL TERMINAL NEGATIVO DE LA FUENTE Y UN SEXTO PUNTO DE UNION ENTRE EL SEGUNDO CONDENSADOR Y EL SEGUNDO DIODO.
