Abstract: The present invention provides a multi-degree-of-freedom conductor depositing system for tokamak toroidal field coil winding packs, belongs to the field of development of toroidal field superconducting coils for nuclear fusion. The multi-degree-of-freedom conductor depositing system is mounted on a winding table and distributed along the contour of the toroidal field coil. The optical proximity switches detect the position signals between the winding table and the bending unit and transmit them to an automatic control system. The multi-degree-of-freedom conductor depositing system is distributed in a spiral shape from the top to the bottom from the position of the bending unit along the direction of coil winding. The conductor is deposited onto the track drive mechanism of the multi-degree-of-freedom conductor depositing device, which has a bidirectional moving and rotating function. This avoids the risk of insulation rupture due to friction between the conductor and the depositing tooling during the coil winding process. It also has the advantages of simple structure, convenient operation and high reliability.

Abstract: In an inductor component, an inductor wire is formed inside a main body. The inductor wire has a circular columnar body extending in the height direction. An end surface of the inductor wire at a first end in the wire extending direction serves as a first external terminal and is exposed at a first terminal surface of the main body. The first external terminal is exposed only at the first terminal surface. An end surface of the inductor wire at a second end in the wire extending direction serves as a second external terminal and is exposed at a second terminal surface of the main body. The second external terminal is exposed only at the second terminal surface.

Abstract: An inductor component is configured such that a lower surface of a first magnetic layer serves as a first terminal surface. A first inductor wire is disposed in the first magnetic layer. The first inductor wire is cylindrical and extends in an up-down direction. A boundary portion is connected to a first internal terminal of the first inductor wire. An upper surface of a second magnetic layer serves as a second terminal surface. A second inductor wire is disposed in the second magnetic layer. The second inductor wire is columnar and extends in the up-down direction. A second internal terminal of the second inductor wire is connected to the boundary portion. The boundary portion serves as a physical boundary between the first inductor wire and the second inductor wire.

Abstract: A current transformer includes a pre-formed core forming a closed loop with a flexible axially wound secondary winding. A continuous length of wire is axially coiled around a flexible bobbin to form a secondary winding. The resulting secondary winding may be slid onto the closed loop of the pre-formed core. The flexibility of the axially wound secondary winding facilitates conformity to a non-linear shape of the pre-formed core.

Abstract: An embedded magnetic component device includes a magnetic core located in a cavity extending into an insulating substrate. The cavity and magnetic core are covered with a cover layer. Through holes extend through the cover layer and the insulating substrate, and are plated to define conductive vias. Metallic traces are provided at exterior surfaces of the cover layer and the insulating substrate to define upper and lower winding layers.
