A charge pump power-factor-correction (CPPFC) power converter is first derived, and its unity power factor condition is then reviewed. A single-stage power-factor-correction electronic ballast using the charge pump concept is analyzed. The design criteria are derived to optimize the electronic ballast based on the steady-state analysis. Constant lamp power operations associated with its control are also discussed. Large signal simulation and experimental results verify the theoretical analysis. It is shown that the designed electronic ballast has 0.995 power factor and 5% total harmonic distortion (THD) with lamp power variation within ±15% when the line input voltage changes ±10%
