A motor vehicle includes a first voltage network and a second voltage network, an operating voltage of the second voltage network being lower than an operating voltage of the voltage network, and two DC voltage converters connecting the second voltage network to the first voltage network, each of the DC voltage converters including a hardware regulator that regulates the operating voltage of the second voltage network, the DC voltage converters being physically separated in the motor vehicle, the hardware regulators of the DC voltage converters being connected via a communication connection having at least one communication line, a first one of the hardware regulators, in operation, sends regulating information via the communication connection to a second one of the hardware regulators, and the second one of the hardware regulators, in operation, performs a regulating operation based on the regulating information sent by the first one of the hardware regulators.
