摘要：

A novel bridgeless Buck power factor correction (PFC) converter with only half dead zones is proposed in this paper. The operation of the proposed PFC converter can be divided into two different modes including Buck mode in positive line cycles and Cuk mode in negative line cycles. Compared with the bridge or bridgeless Buck PFC converter, only half dead zones occur in this proposed PFC converter under the same input and output voltage leading to a higher power factor (PF). This bridgeless PFC converter is designed to work in discontinues conduction mode (DCM). The comparison of performance between the conventional Buck PFC converter and this novel PFC converter has been presented by PSIM simulations and experiments.
