Abstract :
A single-stage power factor correction (PFC) AC/DC converter with a direct energy transfer feature is proposed in this paper. An asymmetric half-bridge topology is used as the DC-DC cell for its inherent ZVS capability, and a direct energy transfer PFC cell is introduced to improve the conversion efficiency. Its operational principles are discussed in detail, and simulation and experimental results are also presented to verify the functionality of this converter.
