Abstract
A multi-phase multi-stage power converter includes a phase module having a power converter module formed of two-pole submodules connected in series and having a plurality of semiconductor switches connected in series, an energy store charged and discharged by the semiconductor switches, a bypass switch short-circuiting the energy store upon exceeding a first limit voltage, and a signal input for a blocking signal opening all semiconductor switches. The submodules are protected from overloading in a simpler manner by connecting a module arrester in parallel with the power converter module. The module arrester limits the power converter voltage like a valve upon exceeding a second limit voltage. The module arrester operates in blocking mode below the second limit voltage and in conducting mode above the second limit voltage. A current limiting the power converter voltage flows through the module arrester in conducting mode.
