| Abstract |
This paper proposes a three-phase six-inductor double-switch PFC circuit which is suitable for high frequency UPS application. This PFC circuit not only achieves high power factor correction in grid-connected mode of UPS, but also improves bus voltage in battery mode of UPS. This new PFC removes the independent boost design in common UPS and the whole cost can be reduced. The topology structure and working procedures of this PFC circuit are introduced and analyzed in detail. The main circuit parameters and LCL filter are designed for a 5kW PFC prototype. The MATLAB simulation and experiment results show that this PFC circuit is easy to control with less switches, and woks in good input power factor and low current harmonic distortion. |
