Abstract

A current converter circuit in a modular multilevel topology includes an AC voltage terminal with a first phase terminal and a further voltage terminal with a plus and a minus terminal. The current converter circuit includes two arms, wherein the first arm connects the first phase terminal and the first terminal and the second arm the second phase terminal and the minus terminal. Each arm includes at least two submodules connected in series, wherein one of the at least two submodules is implemented as analog cell including a passive device as well as an electric circuit. The passive device is connected in parallel to the electric circuit and connected in series with respect to the other one of the at least two submodules.
