  • Patent number: 9608540
    Abstract: The invention relates to a method (60) for controlling an inverter (10) using space-vector pulse width modulation, in particular to control an electric machine (14), said inverter (10) being equipped with a plurality of controllable switches (S) and being designed to provide a polyphase electric current (IU, IV, IW), in particular to supply multiphase electric current to an electric machine (14). In said method, a reference phase angle (alpha_R) is predefined, and the inverter (10) is controlled in such a way that a plurality of different successive switching states (V0-V7) is established for the switches (S) in order to provide the electric current (IU, IV, IW) in the form of a current space vector (I*).

  • Patent number: 8729888
    Abstract: A magnetic transducer configuration may include a permanent magnet element magnetized in its longitudinal direction having a pole transition. The permanent magnet element has a cross section in the pole transition section, which is larger than the cross section of the permanent magnet element in an area outside of the pole transition section. A magnetic position sensor may include a magnetic field sensor array and magnetic transducer configuration. The magnetic field sensor array and the magnetic transducer configuration are situated displaceably in the longitudinal direction in a plane-parallel manner. The magnetic field sensor array has at least one magnetic field sensor lying in a path along which the permanent magnet element moves during displacement of the magnetic transducer configuration.
