An improved passive input current waveshaping method for single-phase diode rectifier

Abstract

This paper presents an improved passive input current waveshaping method for single-phase diode rectifiers (improved method). The simulation results show that the improved method can further lower the input current harmonic components and improve the input power factor of a single-phase diode rectifier as compared with the novel passive input current waveshaping method for single-phase diode rectifiers proposed by P.D. Ziogas (novel method). 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 the simulation results have been verified on a 5 kW experimental models.
