Abstract

This paper presents electronic ballast with dimming capability supplying a 32 W fluorescent lamp. The electronic ballast is a self-oscillating driving circuit and an additional circuit responsible to dimming the fluorescent lamp using a lighting dependent resistor. This luminous sensor measures the luminous flux level and set the lamp power through the voltage gain variation of the resonant filter based on a feedforward control. Simulation and experimental results of the proposed electronic ballast are presented to demonstrate the feasibility of the system.
