Abstract

MODULADOR MODULAR DE ALTA POTENCIA (10) PARA FUENTES DE ILUMINACION PULSATORIAS QUE UTILIZA UN CONVERTIDOR DE PUENTE ENTERO (20) QUE CONVIERTE LA CC SIN REGULAR EN UNA PORTADORA DE 40-50 KHZ MODULADA A UNA FRECUENCIA DE VARIOS CIENTOS A ALGUNOS MILES DE HERCIOS. LA PORTADORA MODULADA ES APLICADA A LA FUENTE DE ILUMINACION (66) MEDIANTE UN TRANSFORMADOR REDUCTOR (50) SEGUIDO POR UN CIRCUITO DE FLITRO DE PASO BAJO (60) QUE SUPRIME LA PORTADORA. EL CONVERTIDOR (20) ES CONTROLADO MEDIANTE UN CONTROL DE MODULACION (42) QUE UTILIZA UNA REALIMENTACION DE SEÑAL DE CORRIENTE DE CARGA INSTANTANEA (72) PARA SEGUIR UNA SEÑAL DE MANDO DE MODULACION (74) Y UNA SEÑAL DE MODO DE INTENSIDAD DE CORRIENTE (76) QUE REPRESENTA LA CORRIENTE DE PRIMARIO DEL TRANSFORMADOR (50) PARA COMPENSAR LAS VARIACIONES DE SALIDA DEL CONVERTIDOR CAUSADAS POR LAS VARIACIONES EN LA TENSION DE ENTRADA.
