Embodiment Construction
[0033] In order to make the technical means and effects realized by the present invention easy to understand, the present invention will be described in detail below with reference to the embodiments and the accompanying drawings.
[0034]
[0035] figure 1 It is a schematic structural diagram of the integrated coil in the embodiment of the present invention.
[0036] like figure 1 As shown, an integrated coil 100 in this embodiment includes an energy transmission coil 1 for energy transmission and an information transmission coil 2 for information transmission disposed in the energy transmission coil 1 .
[0037] The information transmission coil 2 is composed of two vertically stacked DDP coils. The two DDP coils are arranged perpendicular to each other to complete the mutual decoupling. The two D coils in each DDP coil are reversely excited to generate polarized magnetic fields to Decoupled from the energy transfer coil 1 on the outside.
[0038] The energy transmissio...
