Abstract

This paper proposes a non-isolated 24-pulse controlled AC-DC convereter for medium power rating derives. The proposed AC-DC converter configuration consists of a polygon auto transformer to overcome current harmonic problems in AC mains. It improves power quality at AC mains and it meets IEEE-519 standard requirements at varying loads. A set of power quality indices on input AC mains and on DC buses for a load fed from 6-pulse and 12-pulse AC-DC converters is also given to compare their performance. The proposed 24-pulse AC–DC converter is found capable of suppressing up to the 21st harmonics in the supply current along with the power-factor improvement close to unity in the wide operating range of the drive. It involves pulse multiplication in a 12-pulse AC-DC converter. It is observed that input current total harmonic distortion (THD) of less than 8% is possible with the proposed topology of AC-DC converter at varying loads.
