Abstract

A converter arrangement has a converter which can be switched between an AC network and a DC voltage circuit and which has power semiconductor valves that extend between AC voltage connections and DC voltage connections. Each power semiconductor valve has a series connection of bipolar submodules that in turn include power semiconductor devices. The arrangement further includes a star point reactor which is arranged on the AC voltage side of the converter and has impedance coils that are connected to a grounded neutral point. In order to better balance the voltages in the DC circuit, the impedance coils have a common coil core.
