Abstract :
In this paper, a 24-pulse AC-DC converter is designed, modeled and simulated to feed isolated industrial loads. The proposed configuration consists of an isolation transformer based fork connection. 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 bus for load fed from 6-pulse and 12-pulse AC-DC converters is also given to compare their performance. It is observed that input current total harmonic distortion (THD) of less than 5% is possible with the proposed topology of AC-DC converter at varying loads.
