Self-oscillating Electronic Ballast with Lighting Intensity Control
نویسندگان
چکیده
This paper presents electronic ballast with dimming capability supplying a 32 W fluorescent lamp. The electronic ballast is a self-oscillating driving circuit with an additional circuit responsible for dimming the fluorescent lamp based on a signal from a lighting dependent resistor. This luminous sensor measures the luminous flux level and set the lamp power by the voltage gain variation of the resonant filter. Simulation and experimental results of the electronic ballast are presented to demonstrate the feasibility of the proposed system.
