    摘要: The invention relates to a method for detecting an error in a generator unit which has an electric machine (100) with a rotor winding (110), a stator winding (120) transformer-coupled to the rotor winding (110), and a rectifier (130) connected to said stator winding, via which the electric machine (100) is connected to an onboard power supply (150) of a motor vehicle, wherein a decision is made, depending on a magnitude of a correlation (K1, K2) between a curve of an excitation current (IE) flowing through the rotor winding (110) of the electric machine (100) and a curve of a voltage drop (UY, UDF) on one side of the transformer, as to whether the error is present or not.

    摘要: An active converter connected to an electric machine, including arresting circuits to activate a voltage arresting function from a first point-in-time, and which is configured to only activate a load dump reaction upon activation conditions from a second point-in-time, the activation conditions include that it is determined that at the second point-in-time, a supply-side voltage potential applied to an exciter winding of the electric machine is between the voltage potential applied at the first DC voltage terminal and a ground potential, if the exciter winding is disconnected from the voltage potential of the vehicle electrical system voltage and/or a current flowing through the exciter winding is below a current threshold value and/or after an initial activation of a load dump reaction, after which further load dump reactions were activated, more than a predefined period of time has elapsed and/or more than a predefined number of load dump reactions were activated.

The at least one switching time is extended by a predefinable time period if load shedding at the bridge rectifier is determined. Also described is a corresponding rectifier system and a computer program product.

    摘要: A control unit for an electric machine. The control unit has a processing unit and a power output stage connected to the processing unit. The power output stage is connected to outputs of the control unit for stator coils of a stator of the electric machine. The processing unit is designed to supply current to the power output stage for generating a stator field, in particular a rotating magnetic field. The control unit comprises an electrical energy store, in particular an intermediate circuit capacitor or accumulator, connected to the power output stage. The control unit includes an input for a control signal, for example a temperature signal. The processing unit is preferably designed to actuate the power output stage as a function of the temperature signal such that the energy store can be heated by a current application pattern generated by the power output stage. The current application pattern corresponds to a stator field which cannot generate an effective torque or a rotary motion, such as a full revolution of a rotor of the electric machine.
