Abstract
Circuito de alimentación para una instalación de tubos fluorescentes, con un transformador de alta tensión (T) conectado por el lado primario a una tensión de alimentación y carente de entrehierro, habiéndose previsto en el circuito de alimentación, en lugar del entrehierro del transformador, un regulador electrónico (EST) emulador de la función limitadora de corriente que desempeña un entrehierro, caracterizado por ser la tensión de alimentación una tensión alterna, de 300 - 800 Hz de frecuencia, obtenida mediante filtros a partir de una tensión rectangular con modulación senoidal, por poder conectarse un tubo fluorescente al lado secundario del transformador y por estar el transformador dimensionado para la conversión de la tensión de alimentación a alta tensión en la franja de 750 a 15.000 V.
