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.

    本发明涉及一种用于将电网、尤其是直流电网、例如机动车车载电网与单相交变电网或其它直流电网耦合的设备,其中所述设备具有同相直流转换器(B1)和反相直流转换器(B2),所述同相直流转换器和所述反相直流转换器分别具有第一输入和/或输出端以及第二输入和/或输出端,第一直流转换器的第一输入和/或输出端与第一整流器(R1)串联成第一串联电路,而第二直流转换器的第一输入和/或输出端与第二整流器(R2)串联成第二串联电路,第一串联电路和第二串联电路并联并且直流转换器的第二输入和/或输出端并联,而且其中所述串联电路的并联电路的连接端与按照本发明的设备的第一输入和/或输出端(L1、N)连接,并且所述直流转换器的第二输入和/或输出端的并联电路的连接端与所述设备的第二输入和/或输出端(DC1、DC2)连接。
