Japanese Patent JP7343922

B2

The present invention relates to a high-order spatial-temporal symmetric wireless power transmission system and method, the method comprising the following steps: providing an N-order composite coil comprising N resonant circuits, N being an odd number; providing an M-order composite coil comprising M resonant circuits, M being an even number; and connecting scattering capacitors at connection ends of adjacent resonant circuits; coupling the first resonant circuits in the two composite coils to achieve wireless power transmission; connecting a load and an AC power supply; and during a wireless power transmission process, adjusting, according to the change of the coupling strength caused by the change of the coupling distance, the capacitors in the resonant circuits symmetrical to the two first resonant circuits to obtain the optimal transmission efficiency. The present invention eliminates the necessity of frequency tracking in wireless power transmission by utilizing a unique purely real number eigenfrequency exhibited by the odd-order spatial-temporal symmetry and independent of the coupling distance, and achieves the optimal transmission efficiency by adjusting the capacitance of capacitors according to the change of the coupling distance.
