This paper describes a high power factor electronic ballast employing a single power converting stage and a single power switch. The converter provides a high-frequency to supply the lamp. High power factor is achieved through a boost converter operating in a discontinuous conduction mode as a pre-regulator stage. The inverter stage employs a push-pull converter that supplies the LCC filter and Lamps. Operating principles, design equations and experimental results are obtained for the following: 50kHz switching frequency, 110V RMS line voltage, two T1240W fluorescent lamps and 60Hz line frequency.
