Abstract :
A single stage power factor correction AC/DC converter with a direct energy transfer branch is proposed in this paper. An asymmetric half-bridge was used as a DC-DC cell for its inherent ZVS capability, and a direct energy transfer transformer which replaces the conventional boost inductor is introduced to further improve the efficiency.
