摘要
In this paper, the quality of input current waveforms was investigated for a three-phase single-stage full-bridge power factor correction (PFC) converter, which operates in DCM mode. The three-phase input current expression of the PFC converter was derived, and the parameter which can determine the input harmonics current was analyzed in details. Based on them, the method of sixth order harmonics injection was adopted in the control circuit to suppress its input harmonics current. Finally, computer simulation and experimental results prove the validity of the analysis in this paper.
