Wireless power grid is applied in the warehouse or household to build a energy management system. However, the power transfer efficiency depends on the orientation of the receiver. The receiver may be angularly and laterally misaligned that may cause the decrease of the power transfer efficiency. To solve this problem, we proposed multiple transmitters with phase, amplitude and frequency modulation to make the power transfer efficiency more stable. The first part of the thesis presents the wireless power transmission principles including the weak magnetic induction and electromagnetic radiation. In order to solve the orientation problem. We propose the multiple transmitters structure. Therefore, the second part of this thesis shows the design of multiple transmitters structure. We establish an equivalent circuit model and show the results of the power transfer efficiency. By adjusting the phase difference and frequency difference between transmitters, we can solve the orientation problem. Finally, we measure the received power under different rotation angle to ensure the received power is stable. This method can be used to achieve the stable power performance.
