Abstract :
A multi-cell rectifier (MC) structure is presented. The topology is based on power cells implemented with IGCTs thus replacing the SCR standard industry solution for the past 35 years. This rectifier is a reliable, compact, efficient, non-polluting alternative and cost effective solution for electrolytic applications. It injects quasi-sinusoidal input currents and provides unity power factor without the use of passive or active filters. A complete evaluation based on IEEE standards 493-1997 and IEEE C57.18.10 for average down time, failures rates and efficiency is included. For comparison purposes results are shown against conventional systems known for their high efficiency and reliability
