摘要： A magnetic shield for shielding adjacent coils of an ICPT system. One or more conductors are configured to distribute induced eddy currents from the surface of the shield to below the surface and thus reduce heating due to eddy currents. The magnetic shield may be employed to transfer power over rotary couplings, such as the shaft of a wind turbine.

摘要： A power converter is provided which includes at least a first and a second magnetic device equipped with coils and an electrical circuit equipped with a conductor disposed on an imaginary plane, defined between the first and second magnetic devices. If of magnetic fluxes emitted from the coils of the first and second magnetic devices, vectors of components which are oriented in directions of axes of turns of conductors of the coils are defined as a first and a second vector, the first and second magnetic devices are disposed so that an inner product of vectors derived by projecting the first and second vectors on the imaginary plane will be positive. This minimizes electrical noise generated in the electrical circuit.

摘要： In a common-mode choke coil, first annular conductors are helically defined from the lower layer to the upper layer, and first annular conductors are helically defined from the upper layer to the lower layer. Further, second annular conductors are helically defined from the lower layer to the upper layer, and second annular conductors are helically defined from the upper layer to the lower layer. The first annular conductors and the second annular conductors are disposed alternately in a lamination direction. The first annular conductors and the second annular conductors are disposed such that substantial portions of the annular conductors adjacent to each other in the layer direction do not overlap in a planar view. This structure achieves a compact common-mode choke coil with which the loss of normal-mode signals is small, and which is highly capable of removing common-mode noise.
