Abstract

A continuous input current charge pump power factor correction (CIC-CPPFC) electronic ballast is proposed in this paper. Circuit derivation and unity power factor condition using the charge pump concept are derived and analyzed. The power switch only deals with the resonant load current which is the same as the two-stage approach. The developed electronic ballast has continuous input line current so that a small line input filter can be used. The proposed CIC-CPPFC electronic ballast was implemented and tested. It is shown that switching current stress is only half of the integrated single stage electronic ballast. 0.992 power factor and 10.5% THD can be achieved with two 45-watt fluorescent lamps
