A comparative evaluation of hybrid input current waveshaping methods for single-phase rectifier

This paper presents a comparative evaluation of hybrid current waveshaping methods for single-phase rectifier. The simulation results show that the hybrid method can further lower the input current components and THDi of a single-phase diode rectifier as compared with the three passive current waveshaping method by P. D. Ziogas, Ji Yanchao (improved method-1) and H. A. Kazem (improved method-2) . Still the same sequence for improvement is valid in the case of hybrid methods. 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.
