New Multi-Level Converter System for Electric Arc Furnace Applications

A modular multi-level converter (MMC) system based on press-pack IEGT technology has been developed and put into commercial use. The submodules of the new MMC system benefit from the robust press-pack technology used in more than 1,000 high-power drive applications. The fully modular design and a new control architecture allow high flexibility for adaptions on special customer requirements in the power range up to and above 100 MVA. Designs of the main MMC topologies relevant for STATCOM and other steel industry applications will be presented together with performance results from simulations and site measurements, e.g., on EAF flicker reduction.
