Electronic ballasts are implemented for obtaining a high power factor and a good operation
of the lamp; these goals are reached traditionally by implementing multiple stages. On the …

Although compact fluorescent lamps (CFLs) have been in the market for a long time, many of
them do not achieve the same power factor as the incandescent lamps do, which appears to …

Great part of the energy generated in the industrialized world is consumed by lighting, and to
reduce the energy consumption fluorescent lamp are used; to operate a fluorescent lamp …

In this paper a single-switch single-stage charge pump electronic ballast with unity power
factor is introduced for the fluorescent lamps. After a comparison between basic charge …

In this paper a novel class E amplifier with two current sources used to implement high-
power-factor electronic ballast for fluorescent lamps is presented and evaluated. The circuit …

In this chapter, the mathematical, simulation, and experimental results of the proposed
discrete dimming control ballast are presented. The GE non-dimming linear universal ballast …

Electronic ballast for fluorescent lamp with high power factor is traditionally implemented in
two stages: first one to obtain a unity power factor and second one to feed properly the lamp …
