The invention relates to a direct voltage supply system (13) for electromotive consumers, especially on a ship. According to one aspect of the invention, several current units (G, 21) are connected in parallel on the output end and a controllable rectifier or a direct voltage controller (6) is seriesconnected to the current output (5) of every unit comprising a control unit (7) for connection to a voltage regulator (8). The output thereof is coupled to the voltage regulator input to supply a voltage actual value signal (Uist) and an additional signal (Uz). Said output is also connected to the system for the supply thereto. According to another aspect of the invention, each consumer is connected to the system via a power inverter (15) which can be controlled by a regulator (17) via a control input (16), whereby an additional signal (z1) derived from the power inverter input voltage and/or the system voltage is supplied to the input of the regulator, said input being close to the actual value (fist) and the specified value (fsoll). In addition, at least two consumers (19) which are coupled to one another are provided during operation such that an input current flowing from the system in the power inverter or the relevant output of a derived additional signal (fz2) is supplied to the input of the regulator in addition to the actual value and the specified value.
