Abstract

?Un regulador de corriente sin bobina toroide, del tipo retroalimentación incluyendo un filtro y un circuito rectificador, un interruptor y un circuito resonante y una carga de lámpara incluyendo condensadores, donde el filtro y el circuito rectificador están acoplados con los extremos de entrada del interruptor y del circuito resonante con sus extremos de salida; el interruptor y el circuito resonante están acoplados a la carga de la lámpara con sus extremos de salida e incluyen: un circuito disparador formado por las resistencias R1 y R2, un condensador C3, un diodo D5 y un diodo disparador DB3; in circuito de medio puente formado por los transistores Q1 y Q2 y resistencias; y un transformador T de 3 embobinados incluyendo un embobinado primario T3 y dos embobinados secundarios T1 y T2. En el actual regulador de corriente sin bobina toroide, del tipo retroalimentación del actual invento, el interruptor y el circuito resonante emplean un circuito de medio puente de transistores al tiempo con el transformador para efectuar la retroalimentación de impulso de manera que el regulador tiene la ventaja de no tener bobina toroide, lo cual mejora el rendimiento de la carga de la lámpara, simplifica la configuración del circuito y el proceso de fabricación facilitando así la miniaturización de los reguladores electrónicos. <EMI FILE="07113857_1" ID="1" IMF=JPEG HE=50 WI=50 >
