Abstract

A new charge pump power factor correction electronic ballast for high intensity discharge lamps is proposed in this paper. The concept and operation principle of the ballast circuit are first derived. The design guideline for the charge pump capacitors is discussed. The proposed electronic ballast is implemented and tested. No flicker, more than 0.95 power factor and less than 20% THD can be obtained with a 70 W metal halide lamp
