Claim Text:
1. A method for operating a power supply unit for an electrical system of a motor vehicle, the power supply unit including an electric generator, the method comprising: generating a starting voltage by setting the electric generator into rotation without a current being specified by a rotor winding, the electric generator having a stator having a stator winding and a rotor having the rotor winding; selecting, via a field current controller assigned to the rotor winding, a setpoint of a current flowing through the rotor winding; energizing, by the starting voltage, at least one component of the power supply unit or of the vehicle electrical system; and connecting the power supply unit, which is initially disconnected from the vehicle electrical system, to the vehicle electrical system when the starting voltage exceeds a lower threshold value.
