摘要： The invention relates to an expanded control scheme for an electrical machine (2). In particular, it is provided to change specifically into a freewheeling state in the event that only a low torque or a low phase current is to be set at the electrical machine (2). In order to change into the freewheeling state, additionally the actual rotational speed of the electrical machine (2) is taken into consideration.

摘要： The invention relates to controlling an electric drive system, a control range for the switching frequency of a power converter in such a drive system being adaptable when the rotational frequency curve or the torque curve of the electrical machine is taken into account. In this way, psycho-acoustic irritations can be avoided.

摘要： The invention relates to a method for controlling an inverter which is electrically connected to an electric motor, having the following steps: defining a modulated voltage (S1) for the inverter, said voltage being based on a first switching frequency, for operating the electric motor with a current, wherein the current has an electric frequency; determining the electric frequency (S2); changing the first switching frequency (S4) on which the modulated voltage is based to a second switching frequency if a value pair consisting of electric frequency and first switching frequency, or a value pair consisting of electric frequency and a sideband of the first switching frequency, is within at least one defined disturbance range (S3).

摘要： The invention relates to the actuation of an electric machine with a change between time-synchronous PWM clocking and angle-synchronous block clocking It is proposed to provide an angle-synchronous clocking with adjustable voltage indicator length for the transition. In this way, jumps in the operating behavior of the electric machine can be minimized or optionally prevented completely during a change between time-synchronous clocking and angle-synchronous clocking.

摘要： The present invention relates to the control of an electrical power converter. The power converter is controlled with a predefined modulation frequency. This modulation frequency can be variably adjusted. In particular, the modulation frequency can be varied around a basic frequency in a predefined frequency range. The frequency range, in which the modulation frequency is varied, and also the pattern, with which this variation occurs, can be adjusted.

摘要： The invention relates to a method for operating an electric machine. A harmonic manipulated variable with respect to a harmonic of a predetermined frequency occurring during the energization of the electric machine is determined. The electric machine is energized using the determined harmonic manipulated variable by means of a pulse width modulation method. For each period of the pulse width modulation method, the harmonic manipulated variable is determined for both a switch-on operation and a switch-off operation.
