<p>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). A conductor (25) required for a first circuit (20) may be related to earth system (2q) and coupled electrically (61) to a conductor (25 ') required for a second circuit (20') and related to said earth system(2q), wherein said earth system (2q) is connected directly to the rectifying bridge (21) supplied with an alternating current. The circuit arrangement (20) includes a DC/DC-converter (24), constructed of solely a few components, and an energy storage circuit, which is related to a sinus pump unit, a SP-unit, and which has the form of a capacitor (40) adapted for a high capacitance value and/or for a high voltage valve (420V DC).</p> |
