A method for the control of a first current in a first direct voltage network which is connected to a direct voltage converter, wherein energy is transmitted between the first and a second direct voltage network via a transformation unit of the direct voltage converter, wherein a current control is provided for the control of a second current in the second direct voltage network. A second current setpoint is determined from a first current setpoint of the first direct voltage network based on a transfer function of the transformation unit, which second current setpoint is fed to the current control and therefore, due to the transformation ratio of the transformation unit, a first actual current of the current-control-free direct voltage network is controlled.
