Abstract

A two-dimensional transmitting coil array is used to expand receiving area in wireless power transfer with magnetically coupled resonance. The effect of the array is discussed in this paper. The transmitting coil array has more than one resonant frequency due to mutual coupling between transmitting coils. Therefore, we propose a method of designing the transmitting coil array and the receiving coil to keep high transmission efficiency in wider receiving area. The computer analysis and the experiment show the improvement of transmission efficiency of the proposed method.
