A Comparative Evaluation and Design of Input Current Waveshaping Methods for Rectifier

This paper presents a comparative evaluation of passive current waveshaping methods for single-phase rectifier. The simulation results show that the new method can further lower the input current components and THDi of a singlephase diode rectifier as compared with the three passive current waveshaping methods by P. D. Ziogas [5], Ji Yanchao [4] and H. A. Kazem [6]. The relevant input current and voltage waveforms, the input current total harmonic distortion and the input power factor value are derived from the computer simulation or theoretical analysis. A design example is provided and simulation results have been verified on 500 mW experimental models.
