| Abstract |
The increasing number of renewable energy sources and their integration into the medium voltage grid leads to an increasing interest in multilevel structures for the interfacing power electronic converters. A feasible topology for MV applications is the Stacked Multicell Converter (SMC) offering a modular structure and several voltage levels. A robust control, current limiting strategies under grid faults and fault ride-through operation of the converter are required to enable grid integration. In this work, the control of the SMC is investigated concerning balancing of internal DC voltages and handling of asymmetric grid conditions. The control concepts are verified with a scaled experimental test setup consisting of a 7-level SMC connected to the LV grid. |
