High efficiency Bridgeless Unity Power factor CUK converter Topology
View through CrossRef
A step-up bridgeless single phase ac-dc power factor correction (PFC) rectifier based on Cuk 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 Cuk topology. The bridgeless topology results in lower conduction losses as compared with conventional Cuk converter. Simulation and experimental results are presented along with the theoretical analysis.
