Abstract

SE DESCRIBE UN AMPLIFICADOR CONMUTABLE OPERATIVO EN UNA PLURALIDAD DE MODOS DE TENSION QUE DEPENDEN DEL NIVEL DE LA SEÑAL DE ENTRADA. UN CIRCUITO PARA CADA MODO DE TENSION INCLUYE UN IMPULSOR COMUN PARA CADA NIVEL Y UNA PLURALIDAD DE DISPOSITIVOS DE SALIDA DISPUESTOS EN PARALELO. CADA DISPOSITIVO DE SALIDA ES OPERATIVO EN UN NIVEL DE TENSION SELECCIONADO Y ESTA ACOPLADO AL IMPULSOR COMUN PARA EL CORRESPONDIENTE MODO DE TENSION. UN DISPOSITIVO DE SALIDA DE CADA NIVEL ESTA ACOPLADO EN SERIE A UN DISPOSITIVO DE SALIDA DEL SIGUIENTE NIVEL INFERIOR. UN CIRCUITO DE DIODO DE CONMUTACION ESTA ACOPLADO ENTRE SALIDAS EN SERIE CONECTADAS DE CADA DISPOSITIVO DE SALIDA. EN UNA FORMA DE REALIZACION PRACTICA, DIODOS PAREADOS SON ACOPLADOS A CADA NIVEL EN UN TERMINAL COMUN DE LOS DIODOS QUE ESTAN ACOPLADOS A LA ENTRADA. UN REGULADOR ESTA DOTADO PARA OCASIONAR QUE EL IMPULSOR Y LOS DISPOSITIVOS DE SALIDA DE CADA SIGUIENTE NIVEL SUPERIOR VUELVAN AL ANTERIOR CUANDO LA SEÑAL DE ENTRADA CONSIGUE UN NIVEL DE TENSION SELECCIONADO. EL CIRCUITO PROPORCIONA ASI CONMUTACION SUAVE ENTRE NIVELES CON DISTORSION REDUCIDA.
