local.description.resumoSteel is nowadays the world's most important industrial material, with over 1.5 billion tonnes produced annually. In metal industry, rolling is the most widely used steel forming process to provide high production and control of final product. In large drive systems for rolling mills, important requirements such as fast dynamic response and high overload capacity are achieved by using high power converters in medium-voltage range. Among the existing high power multilevel converters, the Neutral Point Clamped (NPC) is the most accepted in industry and the Modular Multilevel Converter (MMC) has been highlighted in recent years for its highest voltage capability, power ratings, high modularity and scalability. This work suggests a methodology of selection and design of high-reliable power converters for critical applications. Two converters are compared with the standard solution: the fault tolerant version of the active NPC converter (FT-ANPC) and the Triple-Star Bridge Cells Modular Multilevel Converter (TSBC-MMC). The study is performed with data taken from a big steel industry in southeastern Brazil. It is demonstrate that FT-ANPC has lower cost. However, TSBC-MMC presents lower power losses and can survive to more failures.
