Abstract :
Charge pump power-factor-correction (CPPFC) technologies, including voltage-source (VS) CPPFC, current-source (CS) CPPFC, and continuous input current (CIC) CPPFC, are presented in this paper. The charge pump concept for achieving PFC and its unity power factor conditions are derived and analyzed, The developed CPPFC techniques use a capacitor to achieve PFC function
