TLDR
In this article, a three-phase multipulse rectifier circuit is described, which uses only passive components and has a lower component count than other rectifier circuits with similar performance.Abstract:
A new converter topology for a three-phase multipulse rectifier circuit is described. This converter draws almost sinusoidal currents from the ac system with very low harmonic content and typically less than 3% total harmonic distortion. The topology uses only passive components and has a lower component count than other rectifier circuits with similar performance. Two six-pulse rectifier bridges are connected in series, fed by a series connection of transformers, to form a 12-pulse system. An additional low power harmonic injection circuit enhances the performance of the circuit to obtain low harmonic current pollution levels that are comparable with those achieved from a 24-pulse rectifier. The circuit operation is explained and experimental results are presented.read more

J.F. Baird,J. Arrilaga +1 more
TL;DR: In this article, a d.c.-ripple reinjection principle was proposed to reduce the harmonic content produced by static convertors, and it was shown by theory and experiment that, using this principle, a six-pulse convertor configuration can be made to operate as a twelvepulse converter from the point of view of a.c. system harmonics.
