Modular power converters play a central role in facing these challenges, not only for grid integration but also to provide flexible services, highly efficient power transmission and safe storage integration. These goals are the key elements in becoming independent from fossil and nuclear power plants in near future. Even if the costs for renewable energy power plants like wind or photovoltaic systems are already competitive to conventional solutions, more flexible operation and further reduction in costs are required for faster global transformation towards sustainable energy systems. The further optimization of modular power converters can be seen as an ideal way to achieve these ambitious goals. It is therefore chosen as the focus of this work. 4950 https://nbn-resolving.org/urn:nbn:de:gbv:8:3-2022-00630-8$xR$3Volltext$534 4961 https://macau.uni-kiel.de/receive/macau_mods_00003058 5051 621.3 5550 FACTS / STATCOM 5550 High-Power Applications 5550 HVDC Transmission 5550 Interleaved Modulation 5550 Modular Multilevel Converter (MMC) 5550 Modular Power Converters 5550 Modulation Techniques 5550 Nearest Level Modulation 5550 Neutral-Point Clamped (NPC) Inverter 5550 Parallel Inverters 5550 Reliability 5550 Renewable Energy Systems 5550 Thermal Management
