Abstract

UNA FUENTE DE SUMINISTRO DE ENERGIA QUE FUNCIONA EN MODO CONMUTADO E INCLUYE UN MODULADOR (U4150) QUE TIENE UNA ENTRADA PARA RECIBIR UNA SEÑAL DE LECTURA Y UNA SALIDA PARA GENERAR UNA SEÑAL MODULADA POR IMPULSOS. HAY UN CONMUTADOR DE SALIDA (Q4100) ACOPLADO AL MODULADOR Y SE CONMUTA SEGUN LA SEÑAL MODULADA POR IMPULSOS. UN GENERADOR (D2, WS2, C5) GENERA UNA TENSION DE ALIMENTACION QUE RESPONDE AL FUNCIONAMIENTO DEL CONMUTADOR. UN CIRCUITO DE REALIMENTACION (FBS) ACOPLADO ENTRE LA SALIDA DEL MODULADOR Y UNA ENTRADA DEL MODULADOR LIMITA EL CICLO DE TRABAJO DE LA SEÑAL MODULADA POR IMPULSOS.
