Abstract: A converter circuit is specified for switching a large number of switching voltage levels, which has n first switching groups for each phase. The nth first switching group is formed by a first and a second power semiconductor switch and the first first to the (n-1)th switching groups are each formed by a first and a second power semiconductor switch and by a capacitor connected thereto. Each of the n first switching groups is connected in series to the respectively adjacent first switching group and the first and second power semiconductor switches in the first first switching group are connected to one another. To reduce the amount of electrical energy stored in the converter circuit, n >= 1 and p second switching groups and p third switching groups are provided, which are each formed by a first and a second power semiconductor switch and by a capacitor connected thereto.
