Abstract :
A high-power-factor electronic ballast is designed to operate fluorescent lamps over a wide temperature range. The electronic ballast extracts a constant power from the AC line source by an embedded power regulation circuit. In addition, the ballast circuit is able to generate sufficiently high starting voltages at different operating temperatures. The design of the electronic ballast is discussed with an illustrative example and experimental results.
