Investigation of Submodule Capacitor Voltage Fluctuation of a Modular Multilevel Converter Under Unbalanced Grid Conditions

Unbalanced grid voltages can occur due to grid faults. Using a Modular Multilevel Converter for distributed generation, fault ride through capability has to be ensured. It especially includes the design of the submodule capacitor. Within this paper, the influence of unbalanced grid conditions on submodule capacitor voltage fluctuation is investigated.
