The invention relates to a device for coupling electrical grids, in particular a direct-current grid, for example a motor vehicle electrical system, to a single-phase alternating-current grid or a further direct-current grid. The device has a non-inverting DC-DC converter (B1) and an inverting DC-DC converter (B2) each having a first input and/or output and a second input and/or output, the firstinput and/or output of the first DC-DC converter is connected in a series with a first converter valve (R1) to form a first series circuit, and the first input and/or output of the second DC-DC converter is connected in a series with a second converter valve (R2) to form a second series circuit; the first and second series circuits are connected in parallel, and the second input and/or output endsof the DC-DC converter are connected in parallel, and the connection points of the parallel circuit of the series circuits are connected to a first input and/or output end (L1, N) of the device according to the invention, and the connection points of the parallel circuit of the second input and/or output ends of the DC-to-DC converters are connected to a second input and/or output end (DC1, DC2)of the device.
