A novel single-stage ZVSZCS PFC half-bridge AC-DC converter with reduced voltage stress

This paper proposes a novel single-stage PFC converter with soft switching, which operates with lower voltage stress, ZVS and ZCS can be achieved for devices at secondary and primary of the transformer respectively. Simulation and experimental results verify the theoretical analysis.
