Asymmetric half bridge soft-switching PFC converter with direct energy transfer
2002 IEEE 33rd Annual IEEE Power Electronics Specialists Conference. Proceedings (Cat. No.02CH37289) - Tập 2 - Trang 676-681 vol.2
Tóm tắt
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.
