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
