Abstract

La presente invención se refiere a un circuito para proporcionar corriente operativa a una lámpara fluorescente, caracterizado porque comprende: primeras terminales para acoplar el circuito a una fuente de energía de corriente alterna (CA) que tiene una frecuencia de energía de CA; terminales para acoplar eléctricamente el circuito con la lámpara; montajes para generar una señal de referencia periódica que tiene una frecuencia substancialmente mayor que la frecuencia de energía de CA; almacenadores de energía conmutable que responden a la señal de referencia para almacenar alternativamente energía de la fuente de energía durante un primer intervalo y descargar cuando menos algo de la energía en la lámpara durante un segundo intervalo; montajes que responden a fluctuaciones en el voltaje de energía CA para variar la proporción del primer y segundo intervalos, para mantener la magnitud de la corriente de lámpara, generalmente constante.
