Abstract
An exemplary method is disclosed for operation of a converter circuit having first and second partial converter systems, the partial converter systems being connected in series to one another via two series-connected inductances. A junction point of the two series-connected inductances forms an output connection. Each partial converter system can include at least one two-pole switching cell, each switching cell having two series-connected controllable bidirectional power semiconductor switches. The power semiconductor switches in the switching cells of the first and second partial converter system are controlled by first and second control signals. A capacitive energy store in the converter circuit can be designed independent of desired current at the output connection of the converter circuit.
