Abstract



An advanced control concept for a Modular
Multilevel Converter (MMC) is presented in this paper. By using a Notch Filter
and a Kalman Filter it is possible to reduce unwanted AC components in the circulating
currents in the MMC significantly. Subsequently the current stress and the conduction
and switching losses in the semiconductors can be minimized.



In the second part of this paper, approaches to
estimate the capacitor voltages are presented. The observability of the
estimators is proven theoretically and in simulations. A disadvantage of the
MMC topology is the demand of a complex and expensive communication system. As
the submodule voltages are estimated, the communication effort between the
submodules and the main controller hardware is significantly reduced.
