Abstract
A motor vehicle, including an electric machine as a drive machine, a high-voltage battery, a high-voltage network to which the electric machine and the high-voltage battery are connected, a low-voltage network having a lower voltage than the high-voltage network, and a DC-DC converter, which connects the low-voltage network and the high-voltage network and is designed for a maximum deliverable rated voltage. The DC-DC converter includes at least two independently usable converter circuits having different maximum power and a control unit. The control unit selects at least one converter circuit to be operated in dependence on a power requirement value of the low-voltage network.
