Embodiment Construction
[0031] The present invention will be further described below with reference to the accompanying drawings and examples, but it is not intended to limit the scope and application of the present invention.
[0032] like figure 2 shown. The charging system is spliced by 4 planar launch pads with planar launch coils of the same specification. Each planar launch coil is made of 10 turns of enamelled copper wire with a wire diameter of 1mm, and the side lengths of each turn are respectively 5.4cm, 12.9cm, 16.4cm, 18.9cm, 20.8cm, 22.3cm, 23.4cm, 24.2cm, 24.6cm, 24.9cm, planar launch coil inductance L TX Both are 119.2uH, the transmitting coil tuning capacitor C TX is 30.7nF, tune it at f 0 The operating frequency of the system is 83.35KHZ. The specifications of the receiving coil in the wireless energy receiver are the same, the diameter is 5cm, and it is formed by winding 40 turns of enamelled copper wire with a wire diameter of 1mm. L 55.2uH, receiving coil tuning capacit...
