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