Flutter the design of structure.
1st, a kind of single-shot penetrates four receiving coil electric automobile static state wireless power supplies, and topological structure is by a big hair
Ray circle and four small receiving coils are formed, and four small receiving coils are positioned over same plane, parallel to transmitting coil.
2nd, it is the advantages of the structure：It is each to receive when four small receiving coils and single big transmitting coil shift
Magnetic field substantially constant, the output voltage substantially constant of system are superimposed between coil and transmitting coil.
3rd, transmitting coil is made up of circular or square multiturn coil, and receiving coil is also by circular or square multiturn coil
Form.
4th, it is sequentially connected after each receiving coil is rectified by the way of series connection, ensures the stabilization of rear end output voltage, this
The beneficial effect of invention is：Simple in construction, highly reliable, output voltage substantially constant, system effectiveness are high, are highly suitable for electronic
Vehicle static wireless charging.
