Embodiment 1
[0054] Specific embodiments will be supplemented with descriptions in the accompanying drawings of the present invention. figure 1 It is a preferred schematic diagram of a 12-turn coil used for making an inductance element according to the present invention. The coil may be composed of a spiral conductive ring, and the width of the spiral conductive ring is not all the same. figure 2 appear as with figure 1 A preferred schematic diagram of the three-layer conductive layer distribution of the coil in . The coil consists of 3 conductive layers. The upper conductive layer has 6 conductive rings, the 6 conductive rings have the same shape but different sizes, and they are arranged neatly; the middle conductive layer has 6 conductive rings, the 6 conductive rings have the same shape but different sizes, and They are arranged neatly; the lower conductive layer has a conductive bridge, and the conductive bridge connects the innermost conductive ring of the middle conductive laye...
Embodiment 2
[0065] Such as image 3 As shown, the inductance coil has three conductive layers, namely the upper conductive layer, the middle conductive layer and the lower conductive layer; the upper conductive layer has two conductive rings 33, 34, these two conductive rings have the same shape but different sizes, and the arrangement The cloth is neat; there are two conductive rings 35 and 36 in the middle conductive layer. These two conductive rings have the same shape but different sizes and are neatly arranged; all the conductive rings of this coil are spiral conductive rings. For the convenience of description, the spiral conductive rings are called for the conductive ring. The coil also includes a conductive bridge configured to connect the inner conductive ring of the middle layer conductive bridge with the second end electrode. Optionally, the conductive bridge can be placed in the upper conductive layer or the middle conductive layer. Optionally, the conductive bridge can also ...
Embodiment 3
[0074] Such as Figure 7 As shown, the inductance element (inductance coil) is composed of two coils according to the present invention, which are respectively the coil on the left and the coil on the right. The coil on the left is rotated 90° counterclockwise, and the coil on the right is rotated 90° clockwise, so that the geometric center of one of the coils has a displacement to the left, and the geometric center of the other coil moves to the right, so that the two coils can be connected in series way to connect. Each coil includes three conductive layers: an upper layer, a middle layer and a lower layer. The coils here all have the same or similar topological design and electrical performance of the coils described in Embodiment 2 of the present invention. However due to the rotation of the coil, the current in Figure 7 The coil shown on the left flows clockwise, while the current in the Figure 7 Flow is counterclockwise in the coil shown on the right. That is to s...
