A DC voltage supply network is described for electric-motor loads, in particular on a ship. A plurality of electricity generation sets are connected in parallel on an output side, and a controllable rectifier or a DC voltage controller is connected downstream of an output of each electricity generation set and has a control input for connection of a voltage regulator. An output of the controllable rectifier or the DC voltage is coupled to an input of the voltage regulator in order to supply a voltage actual value signal and an additional signal, and is connected to the network in order to supply it. The loads are in each case connected to the network via an inverter which can be controlled via a control input by a regulator. In addition to an actual value and the nominal value, an input of the regulator is supplied with an additional signal which is derived from the inverter input voltage and/or the network voltage. When using at least two loads that are coupled to one another, the network provides that, in addition to the actual value and the nominal value, the input of the regulator is supplied with an additional signal, which is derived from the input current flowing from an network into the inverter, or from a relevant power.
