Abstract: The present invention relates to a current distributing circuit arrangement (20, 20?), adapted for charging a plurality of arrays of co-ordinated energy supplying DC-networks (“A” (DC)), (“B” (DC)), wherein the circuit arrangement (20) includes a plurality of setup-related circuits (21, 22, 23, 24) each of which is adapted to a pre selected energy supplying DC-network, (“A” (DC)) with, inter alia, its allocated terminal voltage (350V DC), its allocated capacity and/or its allocated maximized loading current. Respective circuit arrangements (20, 20?) can be allocated an AC-supplied rectifying bridge (21), an after-coupled sinus pump unit (23) and a DC/DC-converter (24) that includes a maximum current limiting circuit (43).
