Abstract | This paper presents a low-cost solution of converting the popularly adopted non-dimmable electronic ballast circuit for fluorescent lamps with self-oscillating series resonant inverter into a dimmable one. Dimming function is achieved by increasing the switching frequency of the inverter from the natural frequency of the resonant tank, so that less energy is coupled to the lamp. Control of the switching frequency is based on deriving an adjustable dc current source from the resonant inductor in the resonant tank to control the operating point of the saturable transformers for driving the switches in the inverter. The overall implementation does not require any integrated circuit. A 17W prototype has been built and studied. Theoretical predictions have been verified with experimental results. The lamp can be dimmed down to 10% of the full brightness. |
