A coil assembly for a wireless power transfer (WPT) system includes a coil carrier tray constructed of a non-conductive, magnetically transparent material that has channels formed therein for receiving a coil. The coil includes a plurality of uninsulated rectangular Litz wire bundles that are woven, braided, or twisted together and then rolled or compressed into a rectangular shape and coated with a non-insulating thin film coating. Each Litz wire bundle, in turn, includes a plurality of uninsulated Litz wire sub-bundles that are woven, braided, or twisted together and then rolled or compressed into a rectangular shape. Each Litz wire sub-bundle, in turn, includes insulated Litz wire strands that are woven, braided, or twisted together and then rolled or compressed into a rectangular shape. The coil design maximizes the amount of conductive material in the channels, maximizing flux density while creating a uniform magnetic flux at the coil surface.

Provided is a magnetic coupling coil component having a high dimensional accuracy for the distance between two coil conductors. A magnetic coupling coil component according to one aspect includes: first and second coil conductors; a first base body portion covering the first coil conductor; and a second base body portion covering the second coil conductor. The first coil conductor has a first winding portion extending around a coil axis. The second coil conductor has a second winding portion extending around the coil axis. The first base body portion has a main body portion and at least one protruding portion. The end surface of the main body portion in a first direction along the coil axis is a first surface. At least one protruding portion protrudes from the first surface. The second coil conductor is positioned such that the second winding portion contacts with at least one protruding portion.

In the embodiments of the present invention, an integrated filter is provided. The integrated filter comprises a cabinet body, and a heat dissipating plate, a resistor and a supporting structure provided in the cabinet body, wherein the resistor is adhered and mounted on a surface of the heat dissipating plate, and the supporting structure is fixedly connected with the heat dissipating plate and is used for fixedly supporting the heat dissipating plate in the cabinet body. As the cabinet body is provided therein with the heat dissipating plate and the resistor is adhered on the surface of the heat dissipating plate, the heat dissipation of the resistor is performed by the heat dissipating plate by which the heat dissipation performance of the integrated filter can be improved. Therefore, it is not necessary for the resistor to use a relatively large steel grid resistor or a heat pipe resistor. As it is possible to use a resistor relatively small in volume, the volume of the cabinet body to be used can be reduced. That is, the volume of the cabinet body in the embodiments of the present invention will be relatively small, facilitating mounting.

A high frequency, high voltage compound helical inductor coil includes a primary coil configured as a helix, a secondary coil configured as a helix and being surrounded by and parallel with the primary coil. A dielectric insulator, configured as a helix, is disposed between and separates the primary coil and the secondary coil. A center conductor may extend axially through the primary and secondary coils and may be attached at a first end to the primary coil and at a second end to the secondary coil.
