摘要：
This paper presents a novel method of reducing harmonic currents on the ac supply side of a three-phase bridge rectifier. The principle of the method is to modify the current waveforms in the dc windings of the converter transformer kv injecting a third harmonic current into the neutral point of the transformer. Passive LC filters connected between the rectifier output and the secondary neutral point act as third harmonic current sources. The effectiveness of the method is confirmed by laboratory recordings.
