Kurzbeschreibung (Abstract)
The modular multilevel converter (MMC) has become one of the most attractive converters for high-power applications such as fusion devices power supplies. This converter, thanks to the discrete-leveled output voltage and its identical submodules (SMs) by which it is composed, represents a promising alternative to replace the flywheel generator (FG) that actually provides electrical power to the toroidal field (TF) coils of ASDEX Upgrade (AUG). Due to the pulsed DC operation of these coils and their high power needs for each experiment, a small-scale adapted version of the MMC is under development with some differences compared to conventional ones: SM capacitors have been replaced with supercapacitor (SC) modules to increase the amount of available stored energy while SMs belonging to different arms are interconnected to simplify their control and increase the reliability of the converter. This poster shows first an overview of the conceptual full-scale converter that could replace in future one of the FGs of AUG and then the development and the operation of a single IGBT full-bridge (FB) SM highlighting advantages and challenges of this configuration.
