摘要： A coupled inductor and a power converter are disclosed. The coupled inductor includes a magnetic core and at least two windings. The magnetic core includes at least two first magnetic cylinders (111, 112), at least one second magnetic cylinder (121), and two opposite magnet yokes (131, 132), the at least two first magnetic cylinders and the at least one second magnetic cylinder are disposed between the two opposite magnet yokes, the at least two windings (151, 152) are respectively located on the at least two first magnetic cylinders, and the at least two windings are in a one-to-one correspondence with the at least two first magnetic cylinders. Leakage inductance of the coupled inductor is increased by adding a second magnetic cylinder between the opposite magnet yokes of the coupled inductor, thereby meeting a requirement on system stability when the coupled inductor is connected to the power converter.

摘要： A small magnetic marker that can be used with high sensitivity both in a generally-called large Barkhausen system and a generally-called high permeability system. The length of the magnetic marker including a soft magnetic material is not more than 70 mm. The soft magnetic material, when an alternating magnetic field of a strength less than 0.20e is applied thereto, causes steep magnetic reversal with a magnetic flux change of more than 8.0 x 10-9 Wb. The variation of magnetic field strength when the soft magnetic material causes a steep magnetization reversal is preferably 0.10e or less.

摘要： A magnetic composition to be used as a magnetic core for a transformer or for high-frequency welding of a laminated tube and a process for producing a magnetic molding from the magnetic composition. The magnetic composition comprises 80 to 95 wt % of ferromagnetic powder, 5 to 20 wt % of highly heat-resistant thermosetting resin powder, and 0.1 to 1 wt % of a metal chelate compound. All of these powers are mixed together and molded under heat and pressure to produce a magnetic molding. The composition enables molding of materials of complicated form at low tempertures, and the obtained moldings have excellent heat resistance, mechanical strength, mechanical workability, and initial magnetic permeability.

摘要： The present invention relates to a magnetic manipulation and navigation system for moving a magnetic element through a body comprising at least six electromagnets (24) with soft-magnetic cores arranged in a predetermined position to said body. It allows for the operation of one or more of the electromagnets in the non-linear regime of the magnetization curve of the cores. The system comprises at least one magnetic field sensor (104) at one or more predetermined positions outside of the operating region. While during operation in the linear region no feedback is required to set the magnetic field strength, during operation in the non-linear region feedback from the magnetic field sensors is used for closed-loop control. The system allows for operation in two separate modes, an open-loop mode operation in the linear regime for fast control signals such as they are required for stabilization during displacement of the magnetic element and a closed-loop operation in the non-linear regime for higher field strengths such as they may be required to apply forces and moments on the magnetic element while it is in contact with a surface.
