A multicell rectifier (MC) structure with N + 2 redundancy is presented. The topology is based on power cells implemented with the integrated gate commutated thyristors (IGCTs) to challenge the SCR standard industry solution for the past 35 years. This rectifier is a reliable, compact, efficient, nonpolluting alternative and cost-effective solution for electrolytic applications. Its structure, based on power cells, enables load shedding to enhance power delivery even in the event of power cell failures. It supplies quasi-sinusoidal input currents and provides utility power factor without the use of passive or active filters. A complete evaluation based on IEEE standards 493-1997 and IEEE C57.18.10 is presented, and areas for downtime, failures rate, and efficiency is included. For comparison purposes, results are shown against conventional systems known for their high efficiency and reliability.
