Presents CPPFC techniques achieving 0.99 power factor in electronic ballasts, suggesting excellent efficiency.
For pt.I see ibid., vol.15, no.1, p.121-9 (2000). Charge pump power-factor-correction (CPPFC) converters using voltage-source (VS) CPPFC, current-source (CS) CPPFC, and continuous input current (CIC) CPPFC techniques are developed in this paper. Design considerations and the performance of the CPPFC electronic ballasts are discussed, analyzed, and evaluated. The experimental results show that 0.99 power factor and 10% total harmonic distortion (THD) can be achieved. It is shown that the CPPFC techniques are very attractive.
