A new one-switch three phase power factor corrected (PFC) rectifier is presented in this paper. The proposed 3-phase ac-dc converter is based on Ĉuk topology. Proper feedback control of the circuit can maintain high power factor and low input current total harmonic distortion (THD). Use of minimum number of control switch in the proposed power conversion circuit reduces components, drivers drive isolation...
An input switch based modular Single Ended Primary Inductor (SEPIC) three phase AC-DC converter is proposed in this paper. The proposed rectifier has the advantage of step-up/down voltage gain with boost input stage. Input boost stage allows input current shaping accompanied by power factor correction. The topology will also provide possible capacitive isolation of input/output sides of the converter...
