The invention relates to a converter circuit (4). The converter circuit comprises two sub-modules (24, 26) that are connected in series, for receiving electrical power from a power source (8) via an inductor (22), wherein the power source (8) supplies direct current (18). Each sub-module (24, 26) has single phase half bridge on input sides and single phase full bridge on load sides of load (10). An intermediate circuit capacitor is connected parallel to half and full bridges. At least one electrical line in each sub-module (24, 26) comprises a plurality of current paths (42, 46) connected in parallel.
