摘要
The invention relates to a submodule (1) for a modular multilevel converter (2), having: - nine semiconductor switches (S1, S2, S3, S4, S5, S6, S7, S8, S9) that can be switched off, - four capacitors (C1,1, C1,2, C2,1, C2,2), - six network nodes (N1, N2, N3, N4, N5, N6), - and two terminals (11, 12), the components being mounted such that different voltages are generated between the terminals (11, 12) of the submodule (1) when the semiconductor switches that can be switched off are controlled. According to the invention, the behavior of the converter and of the submodule (1) in the event of a fault is substantially improved.
