A Modular Three Phase Power Factor Correction (PFC) Approach with Two Single Phase PFC Stages and an Electronic Phase Shifter Conference Paper uri icon


  • © 2015 IEEE. In this paper a modular three phase power factor corrections (PFC) structure is proposed. The proposed topology employs two single phase PFC stages that are independently controlled. To secure the single phase PFC independent operation; an electronic phase shifter (EPS) is employed to modify the three phase input voltages to two single phase input voltages. The electronic phase shifter replaces a conventional phase shifter transformer that improves the overall power density. Simulation results for a 12kW three phase PFC are included and an experimental results for a scale down prototype are discussed. A design example is included to benchmark the proposed solution.
