A method for calculating harmonic currents of a three-phase bridge uncontrolled rectifier with DC filter

Masaaki Sakui, Hiroshi Fujita, Mitsuo Shioya

Abstract

A practical method is proposed for calculating the harmonic currents of a three-phase bridge uncontrolled rectifier with a DC filter, taking into account the AC source reactance. The method is based on the frequency-domain method and the rectifier switching functions. Analytical equations for the harmonic currents on both the DC and AC sides are derived. The validity of the method is demonstrated by comparison with the results of time simulation. The approach can be extended to the harmonic analysis of a thyristor rectifier as well as a rectifier with unbalanced line conditions.>
