Harmonic Analysis of 6-Pulse Diode Bridge Rectifier Circuits

  1. Mohamed Mostafa Saied

Abstract

This paper analyzes the steady-state harmonic performance of the six-diode, 3-phase rectifier bridge circuits. A procedure for determining the frequency spectra of the different voltages and currents within the bridge circuit, resulting from a 60-Hz 3-phase supply, is presented. The effect of the smoothing shunt-capacitor is also demonstrated. Based on a Mathematica code, the paper presents the results of a comprehensive list of case studies. The procedure can handle unsymmetrical voltage sources and the presence of nonlinear circuit elements.Keywords: Analytical models, Bridge, Diodes, Frequency spectra, Mathematica, Power electronics, 6-pulse 3-phase, Rectifier circuits, Steady-state analysis
