摘要： A description is given of an arrangement for determining the position of a magnetic-field-sensitive sensor unit in the magnetic field of a magnet arrangement having an at least substantially bar-shaped contour along an at least substantially rectilinear motion coordinate that extends parallel to a longitudinal axis of the at least substantially bar-shaped contour, in which the magnetic-field-sensitive sensor unit is intended to measure a component of the magnetic field which extends in a plane that is at least substantially parallel to the longitudinal axis of the at least substantially bar-shaped contour in a manner at least substantially perpendicular to this longitudinal axis, and the magnet arrangement has a magnetic north pole in the region of a first end of the at least substantially bar-shaped contour, a magnetic south pole in the region of a second end of the at least substantially bar-shaped contour, and a narrowing of the at least substantially bar-shaped contour in the central region extending between the north pole and the south pole. Better use can thereby be made of the dimension of the magnet arrangement than for a range that can be used for position measurement.

摘要： The disclosure relates to a method for charging an intermediate circuit capacitor in an electric drive unit comprising an electric motor. The intermediate circuit capacitor is charged by an intermediate circuit current that is supplied by a battery. The output voltage of the battery is settable to one or more voltage values. A target value of the intermediate circuit current is determined, and an actual value of the intermediate circuit current is ascertained. The actual value of the intermediate circuit current is then compared with the target value of the intermediate circuit current. An optimal output voltage of the battery is determined on the basis of the comparison of the actual value of the intermediate circuit current with the target value of the intermediate circuit current. Then, the optimal output voltage of the battery is set.

摘要： A signal processor for removing at least one unintended signal component from an input signal (ua) is proposed. The signal processor includes a filter device (130) and a processing device (150). The filter device (130) filters the input signal (uâ) and generates a filtered signal (uf), which includes the unintended signal component to be removed. The processing device (150) generates an output signal (um), which indicates a deviation of the input signal (ua) from the filtered input signal (uf). By detecting the unintended signal component first an removing this component from the input signal (uâ), the input signal will not be manipulated directly but the unintended signal component in the input signal (uâ) will be compensated. This allows to remove the unintended component from the input signal (uâ) with less distortions of the interesting components in the input signal (uâ).
