Abstract

In this paper, the current Harmonics in the 12-Pulse uncontrolled AC/DC converter fed AC Drives was studied. The 12-pulse Δ-Y type AC/DC converter will keep a balanced voltage with 30° phase shifted at the low coupling coefficient condition. Different converter arrangements for 12-pulse-based rectification are also studied and a novel harmonic mitigator capable of suppressing fifth, seventh, and 11^th (most dominant harmonics) in the supply current is presented and describes the simulations of harmonics from 12-pulse adjustable speed drives. The simulations are done in Mat lab by sim-link circuit simulator. Finally, 585 kW, 690V, 12-pulse AC Drive Harmonic´s measurements were presented.
