针对传统四线圈磁耦合式非接触电能传输系统的输出功率和效率较低等问题，提出了一种平面螺旋型四线圈磁耦合式非接触电能传输系统。并运用MATLAB仿真软件，对平面螺旋型四线圈和传统四线圈非接触电能传输系统的输出功率和传输距离、传输效率和传输距离之间的关系进行了对比分析。结果表明：在相同距离时，平面螺旋型四线圈磁耦合式非接触电能传输系统的传输功率和传输效率均高于传统四线圈传输系统的，且平面螺旋型四线圈磁耦合式非接触电能传输系统的传输效率比传统四线圈传输系统的高3%。

英文摘要：

In view of the low output power and output efficiency exhibited by the conventional four-coil magnetic coupling contactless power transmission system,a planar spiral four-coil magnetic coupling contactless power transmission system has been proposed.A comparative analysis has been made between its output power and transmission distance,as well as its transmission efficiency and transmission distance by using MATLAB simulation software.The results show that,with the distance a constant,the output power and transmission efficiency of the planar spiral four-coil magnetic coupling contactless power transmission system are3%higher than those of the traditional four-coil transmission system.
