For demanding future applications in power transmission - like grid connection of large off-shore wind parks, solar thermic power generation or power supply of mega cities - there is a global need for advanced power electronic systems. The novel concept of Modular Multilevel Converter (M2C) offers superior characteristics for these applications. Its operations for HVDC-systems is explained and investigated with respect to new requirements - including failure management in Multi-terminal-HVDC-Networks.
