Abstract
A circuitry arrangement includes two-pole connectors for connecting a battery and a further voltage source. The plus pole of one connector and the minus pole of the other connector are directly connected to a plus pole and a minus pole of a DC voltage link. The plus and minus poles of the one connector are connected via a first parallel circuit of a switch and a diode and a first choke connected in series. The minus and plus poles of the other connector are connected via a second parallel circuit of a switch and a diode and a second choke connected in series. A connection between choke ends of the two parallel circuits is electrically conductive at least for alternating currents. The two chokes are magnetically coupled in that their winding senses on a common magnetic core are equal as viewed from the connection between the two parallel circuits.
