Compact Fluorescent Lamp

A novel single-switch high-power-factor electronic ballast is designed for compact fluorescent lamps. The circuit configuration is originated from the integration of a buck-boost power-factor-corrector (PFC) and a Class-E load resonant inverter. Design equations are derived based on fundamental approximation and computer analyses are performed to determine circuit parameters. By operating the buck-boost converter at discontinuous conduction mode (DCM), the electronic ballast can achieve nearly unity power factor. With carefully designed circuit parameters, the active power switch can be switched on at relatively low voltage, leading to a high circuit efficiency. A prototype for a 27-W compact fluorescent lamp was built and tested to verify the analytical predictions. Satisfactory performances are obtained from the experimental results.

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 is based on the class E amplifier with two current sources, one of them was implemented using the main input voltage and the other by means of a bulk capacitor charged from the resonant tank of the class E amplifier. This topology presents a high power factor and low current crest factor and only uses one switch with zero voltage switching. Design guidelines are presented and a 300-kHz electronic ballast for a 32-W compact fluorescent lamp was designed and tested.
