Abstract
Various embodiments include a device for coupling two DC grids comprising source-side and load-side capacitances comprising: a switching device for current regulation, the switching device including two series-connected switching modules; wherein each of the switching modules includes at least one controllable semiconductor switching element connected in parallel to a respective series circuit comprising a resistor and a capacitor; and a control unit. The control unit is programmed to: switch the controllable semiconductor switching element of one of the two switching modules on and at the same time switch the controllable semiconductor switching element of the other of the two switching modules off; switch the controllable semiconductor switching element of the other of the two switching modules on and at the same time switch the controllable semiconductor switching element of the one of the two switching modules off; repeat steps a) and b) until the voltages of the source-side and load-side capacitances have aligned with one another; and switch the controllable semiconductor switching elements of the two switching modules on.
