英文摘要：

Different primary-secondary coil couple of wireless power transmission system were presented and analyzed. The primary coils＇ parameters influenced on the inductive uniform magnetic field were evaluated and the ampere-turns conditions were achieved. The power transfer efficiency and transmission power were calculated and the corresponding design demands were obtained. To promote the space utilization ratio,the secondary coils＇ parameters were optimized,and the efficiency and the stability of each couple were compared. The experimental results show that 3D-primary and 1D-secondary coil couple could provide at least 420 m W power in a volume of Φ12× 13 mm,with efficiency of no less than 9. 38% and stability of 21. 6%,which is better than others.
