Embodiment Construction
[0047] Combine below Figure 5 to Figure 11 , the multi-function mode circuit of the present invention will be described in detail.
[0048] A multifunctional mode circuit of the present invention includes a wireless power transmission coil with M primary coils and M external terminals, and M≥2, wherein the M primary coils are connected in series in sequence, and every two adjacent primary coils There are coil connection switches between the side coils, and at the same time, the two ends of each coil connection switch are respectively connected to two adjacent external terminals through the terminal connection switch, and the M primary side coils are also respectively connected to M external terminals through compensation capacitors. The terminals are connected in one-to-one correspondence. Therefore, by adjusting the switch state of each switch, the circuit can be in a variety of different working modes.
[0049] exist Figure 5 In the illustrated embodiment, the aforement...
