Abstract

LA INVENCION SE REFIERE A U MODULADOR DE SUMINISTRO DE ENERGIA PARA UN TRANSMISOR DE RADIO QUE TIENE UNA IMPEDANCIA DE ENTRADA PRORRATEADA Y UNA CONMUTACION AMORTIGUADA DE LOS MODULOS DE ENERGIA. UN DISPOSITIVO EN SERIE DE MODULOS DE SUMINISTRO DE ENERGIA, CONVENCIONALMENTE DISPUESTO EN UNA CASCADA DE DIODOS, INCLUYE INDUCTORES INDIVIDUALES PARA PRORRATEAR LA IMPEDANCIA DE ENTRADA DE LOS SUMINISTROS DE ENERGIA DE CONMUTACION. LA SECUENCIA DE CONMUTACION DE LOS SUMINISTROS DE ENERGIA ES CONTROLADA POR UNA MEMORIA FIFO, ESTANDO DISPUESTOS LOS SUMINISTROS DE ENERGIA SECUENCIALMENTE ADYACENTES DE FORMA FISICAMENTE REMOTA DE MANERA QUE LOS TRASIENTES DE CORRIENTES Y LAS CARGAS TERMICAS SEAN DISTRIBUIDOS MAS UNIFORMEMENTE.
