In the process of using the coil, if the need to fine tune, should consider the wireless charging coil trimming method. What is the wireless charging coil trimming method?
Some coils in the use of the process, the need to fine tune, depending on the number of coil turns is very inconvenient, therefore, the choice should take into account the fine-tuning method. For example, a single coil can be removed by the end of the number of stranded coil method, that is, in advance of the coil at the end of 3 laps around the circle, in the fine-tuning, the position of the movement can change the inductance. Practice has proved that this method can be adjusted to achieve fine tuning 2%- + 3% inductance. The coil used in HF and VHF circuits, often set aside half circle as trimming, remove or turn the half circle of the inductance change, realize the wireless charging coil tuning. The fine tuning of the multilayer coil can be achieved by moving the relative distance of a segment, and the number of movable segments should be 20%-30% of the total number of coils. Practice has proved: this fine tuning range of up to 10%-15%. The coil with magnetic core can be adjusted by adjusting the position of the coil in the coil. Adjustable coil should be installed in the machine easy to adjust the position, in order to adjust the inductance of the coil to achieve the best working condition.
