| Abstract |
Further progress of Modular Multilevel Converters (MMC) is mainly related to advanced submodule topologies (SM), semiconductors (SiC) and improved control concepts. Fully electronic failure management for external failures (i.e. DC-short circuit) and protection against internal failures of the converter are key issues. A new submodule for MMC is presented, which meets these requirements. In addition, a novel SiC-JFET super-cascode is investigated, suitable for these and other applications. |
