Abstract

This paper proposes a wide output range single-stage soft-switched AC-DC power factor correction (PFC) converter topology. The converter is an isolated active-clamp boost PFC converter with active switches on the secondary side. The active switches of the secondary side are used to control the voltage and current at the output port. The operation of the proposed converter topology and a control strategy suited for battery charging is elaborated. The steady-state analysis of the proposed topology is presented, which is used to determine current stresses and soft-switching boundaries and perform power flow analysis. Switching circuit simulation results and experimental results from a 1 kW rated hardware prototype have been shown to validate the topology and converter operation. © 2024 IEEE.
