    摘要: An ignition coil includes primary and secondary coils, a center core inserted into a center hole of the primary coil and a center hole of the secondary coil, an annular side core that forms a magnetic circuit through which a first magnetic flux A generated by the primary coil by being joined to the center core permeates, and a permanent magnet that is disposed between the center core and the side core and that emits a second magnetic flux B directed opposite to the first magnetic flux A to apply a magnetic bias. The side core includes protruded portions that protrude towards lateral sides of a T-shaped horizontal portion of the center core, and gaps are provided between the lateral sides of the T-shaped horizontal portion of the center core and the protruded portions of the side core.

    摘要: A technique is provided for detecting a magnetic characteristic variable in particular the magnetic field strength in a section of a core permeated by a magnetic flux. A portion of the magnetic flux is branched off from the core and passed via a magnetic shunt branch, in which at least one non-ferromagnetic gap is formed. A shunt part is disposed in the shunt branch, wherein the magnetic material of the shunt part is not saturated. At least one section of the shunt part is wound with at least one sensor coil in which the branched-off portion of the magnetic flux generates a sensor signal by induction. The magnetic characteristic variable is determined from the branched-off portion of the magnetic flux or a variable derived therefrom using a sensor and evaluation device to which the sensor signal is fed.

    摘要: Current compensated inductors have a substantially closed core, which deviates from the toroidal core design such that increased leakage flux is achieved and, at the same time, the further advantages of a conventional toroidal core geometry are maintained. In particular, the current-compensated inductors according to the invention can be produced efficiently by means of automation without subsequent process steps for fitting shunt elements being required.
