Inhalt:
This paper presents a novel control structure for Modular Multilevel Converters (MMC). It enables improved dynamic and steady state behavior of the (internal) arm energies and arm currents. Minimized capacitor size and a reduction of control complexity are main advantages. The new method is based on space vector partitioning into twelve (or more) sectors in combination with multiplexing of the control variables.
