    摘要: A wireless resonant powering device 1 according to the invention comprises a first inductor winding 3, which is arranged to form a transformer 9 with the inductor winding 13 of the energizable load 11. The first inductor winding 3 is arranged to form a resonant circuit 5, which may comprise a suitable plurality of electric capacitances and coils. The components of the resonant circuit 5 are selected such that the magnetic energy received by the inductor winding 13 damps the energy flow in the resonant circuit so that the induced voltage in the inductor winding 13 is substantially constant and is independent of the magnetic coupling between the first inductor winding 3 and the inductor winding 13 at the operating frequency of the driving means 6. The resonant circuit is driven by the driving means 6, comprising a control unit 6c arranged to induce an alternating voltage between a first semiconductor switch 6a and a second semiconductor switch 6b. At the output of the transformer 9 an alternating voltage is generated, which is rectified to a DC-voltage by a diode rectifier, filtered by an output capacitance. The resonant circuit 5 is operable on its coupling independent point by the driving means 6. This figure schematically illustrates a situation, where a variable coupling between the first inductor winding 3 and the inductor winding 13 exists. The invention further relates to a wireless inductive powering device, an energizable load, a wireless system and a method for wireless power transfer.

    摘要: For the offset calibration of a magnetoresistive angle sensor for the determination of the directions of magnetic fields, the sensor includes a Wheatstone bridge with at least four magnetoresistive resistors. The Wheatstone bridge receives an input signal at its input side, in particular an input voltage, and supplies an angle signal at its output side, in particular an angle voltage, in dependence on the direction of a magnetic field which acts on the Wheatstone bridge. The Wheatstone bridge includes a first and a second pair of mutually opposed, substantially parallel magnetoresistive resistors, the first and the second pair being arranged substantially at right angles to one another, while the direction of the magnetic field can be determined from the angle signal supplied by the Wheatstone bridge by means of an evaluation circuit. In a first step the Wheatstone bridge is acted upon by a direct magnetic field which is so aligned that it is neither substantially perpendicular to the magnetoresistive resistors of the first pair nor substantially perpendicular to the magnetoresistive resistors of the second pair of the Wheatstone bridge. In a second step the direct magnetic field is removed, and in a third step an evaluation circuit determines an offset calibration signal, the angle signal supplied by the Wheatstone bridge without direct magnetic field being a measure for the offset of the Wheatstone bridge.

    摘要: The invention relates an electrical device for providing an output depending on an electrical input. The electrical device (1) is adapted to provide a constant output, if the electrical input is in a first electrical input range, and a dependent output, if the electrical input is in a second electrical input range, wherein the dependent output depends on the electrical input. The output can therefore remain constant, even if the electrical input, which is preferentially a DC grid voltage, fluctuates within the first electrical input range. Moreover, in the second electrical input range the output can be controlled by just controlling the electrical input like the DC grid voltage, without necessarily requiring an additional control construction of the electrical device. A resistance against fluctuations of the electrical input and a controllability of the output can therefore be realized in a relatively simple way.
