Abstract :
In this paper, a 1-phase power factor correction soft switched converter is presented. A novel zero voltage transition (ZVT) technique is used for zero voltage / current switching of the main and auxiliary switches. The operating modes, analysis and design considerations for the proposed converter are explained. To evaluate the performance of the proposed converter, simulation and experimental results for a 400 V, 0.5 kW prototype converter are presented. The proposed converter operates at almost unity power factor with increased efficiency.
