Abstract :
In this paper, an improved continuous-current-mode, single-stage, power-factor-correction (PFC) technique is proposed. The proposed technique employs an auxiliary low-frequency switch to achieve a low input harmonic-current, low energy-storage-capacitor voltage stress, and high conversion efficiency. The improved performance was verified experimentally.
