A method for controlling a multiphase machine which is connected to a direct current voltage source. The machine has a DC link which is provided with a DC link capacitor, phase windings, and a high side switch and a low side switch for each phase. The switches associated with the individual phases are acted on by control signals from a control unit. For reducing the DC link current, the control unit provides block-shaped control signals for the switches associated with the individual phases in such a way that trapezoidal or pulsed phase currents are predefined, at least one phase current is connected at any point in time in each control cycle, and the value of the amplitude ratio of the predefined phase currents is selected in such a way that the connected phase currents correspond to the instantaneous current of the direct current voltage source. |
