A three-phase isolated full-bridge boost power factor correction (PFC) converter with a flyback passive auxiliary converter is presented and investigated. The PFC converter operates in discontinuous conduction mode (DCM), it can achieve zero voltage turning off for the upper switches and zero voltage turning on for the lower switches. With the adoption of the passive auxiliary converter, the voltage...
A three-phase single-stage full-bridge power factor correction converter is presented in this paper. The converter could achieve power factor correction and AC/DC power conversion in one stage circuit. It could achieve electrical isolation between input and output sides. The voltage stress of each switch is reduced due to the adopting of the active clamp circuit. By using soft-switching techniques,...
