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).

Abstract: The present invention comprises an electronic element (2a), fitted or adapted for an electric circuitry or circuit arrangement (1), where said circuitry inter alia is constituted by a voltage source (1a, 1b), a supply voltage and a current feeding unit (2) switching on or switching off a load, and an interlocking circuit (2a) connected between the unit and the load (1c), where said interlocking circuit is assigned a function fitted or adapted for switching on or switching off current, in order to achieve a switch-on or switch-off free from sparks or arcs of the load current (“Ib”) of a selected load (1c) via said element (2a). Said interlocking circuit is structured as an electronic element where a switch-on of voltage to said electronic element (2a) causes the activation of circuits belonging to the element in order to, after the switch-on of voltage and by a trigger signal, cause the load current (“Ib”) to said load (1c) to be increased.
