Cryo-MMC - a Modular Multilevel Converter with Superconducting Coupled Arm Coils

, 2022
In this thesis, we study a Modular Multilevel Converter (MMC) with high temperature superconducting (HTS) directly-coupled arm coils that we proposed to call cryo-MMC. We design directly-coupled HTS arm coils and their cooling system for a cryo-MMC in a point-to-point high-voltage direct-current (HVDC) link rated at ±320 kV and 1 GW.

Closed-loop control and data- recording of a modular-multilevel converter (MMC)

, 2022
Modular multilevel converters (MMCs) are the preferred converter solution in flexible ac transmission systems (FACTS) and high-voltage direct current (HVDC) applications. This is due to the high quality of the voltage and current signals, lower overall losses, and fewer problems with switching-related EMI.
