Abstract

CIRCUITO CONVERTIDOR DE ALIMENTACION, CONSISTE EN UN CONVERTIDOR DC/DC AISLADO, CONTROLADO POR MODULACION DE ANCHURA DE IMPULSOS (PWM), EN MODO CORRIENTE Y CON TOPOLOGIA DOBLE-DIRECTO EN CONTRAFASE, CON DUPLICACION DE INDUCTORES DE ALMACENAMIENTO DE ENERGIA Y DESMAGNETIZACION RESONANTE DE LOS NUCLEOS DE LOS TRANSFORMADORES, PERMITIENDO MANTENER UN FUNCIONAMIENTO ADECUADO EN UNA FRECUENCIA DE CONMUTACION MUY ALTA, UTILIZANDO COMPONENTES DE ALTURA REDUCIDA EN TAMAÑO PEQUEÑO Y FUNCIONANDO A FRECUENCIA DE CONMUTACION FIJA, MANTENIENDO LOS ARMONICOS GENERADOS FUERA DE LA BANDA EN LA QUE ES SENSIBLE LA CIRCUITERIA ANALOGICA DEL RESTO DE LA PLACA, PROPORCIONANDO TRES TENSIONES DIFERENTES DE ALIMENTACION, AISLADAS DE LA ENTRADA AUNQUE NO ENTRE SI, CONSTITUIDAS COMO UNA PRINCIPAL Y DOS AUXILIARES.
