High Efficiency Bridgeless Sepic Rectifier for Power Factor Correction
نویسندگان
چکیده
A step-up bridgeless single phase ac-dc power factor correction (PFC) rectifier based on sepic topology is proposed for high voltage battery charger application. The proposed topology consists of common input stage and parallel output stages. It utilizes one control signal over the whole line cycle. In addition, the proposed converter exhibits low inrush current and low magnetic emissions as classical sepic topology. The bridgeless topology results in lower conduction losses as compared with conventional sepic converter. Simulation results are presented along with the theoretical analysis.
