Abstract :
A flyback-based single-stage power factor correction scheme with time-multiplexing control is proposed. Main and auxiliary switches operate independently within a same time cycle. High power factor and low output line-frequency voltage ripple are both obtained in discontinuous conduction mode. The major output power is directly delivered to the load. A single transformer is used for the power conversion. The main and auxiliary outputs are fully isolated. The experimental results confirm the effectiveness of the proposed scheme with high power factor and tight output regulation.
