Abstract

EL MODULADOR POR ANCHOS DE IMPULSOS DESCRITO SE COMPONE DE UN GENERADOR DE IMPULSOS RECTANGULARES (4), UN CIRCUITO MULTIVIBRADOR MONOESTABLE REDISPARABLE (6), UNA COMPUERTA (5) Y UNA FUENTE DE ALIMENTACION REGULABLE (1) CON UN CONDENSADOR (7), COMO ORGANO TEMPORIZADOR PARA EL CIRCUITO MULTIVIBRADOR (6). SI EL MODULADOR ESTA BASADO EN COMPONENTES ESTANDAR EN LA TECNICA CMOS Y DE OTROS COMPONENTES EXTERNOS, SU PERDIDA DE POTENCIA ESTA POR DEBAJO DE 10M MW. COMPLETADO CON UN AMPLIFICADOR DE REGULACION (2), BASADO ASIMISMO EN LA TECNICA CMOS, Y CON UNA FUENTE DE ALIMENTACION DE REFERENCIA (3), EL MODULADOR POR ANCHOS DE IMPULSOS,PUEDE SER UTILIZADO OPORTUNAMENTE EN EL CIRCUITO DE REGULACION EN CONVERTIDORES DE CORRIENTE CONTINUA POR IMPULSOS. LA PROPIA PERDIDA DE POTENCIA DE SEMEJANTE CONVERTIDOR DE CORRIENTE CONTINUA SE ENCUENTRA ENTONCES TODAVIA POR DEBAJO DE 26 MW.
