Title Comprehensive Optimize of Transfer Capability of Magnetic Resonance Coupling Wireless Electrical Energy Transfer
Abstract Magnetic resonance coupling wireless electrical energy transfer is a kind of technology which use electromagnetic wave to transfer energy. It owns great prospect. But it still has a lot of problem as high efficiency and high-power transfer usually can’t reach together. Using impedance matching and modeling, optimize compute a part of the main parameter of magnetic resonance coupling wireless electrical energy transfer system, and reach the optimize result. Then use Orcad and Matlab to emulate the result to find whether it is true or false; And use emulating curve to optimize the other parameter, and find the best short-cut process in special situation. Find the representation of M12 to optimize it, and using impedance matching find the representation of system electrical energy transfer efficiency and way to optimize it. Optimization is successful and ground for the following work.

无线电能传输是利用电磁波进行非接触能量传输的技术，由于其传输能量不依赖介质，能够在很多难以利用导线传输的复杂环境下传输电能，并且节省空间，从电力被发现以来一直是人们想要实现的技术之一。其目前主要包含电磁感应耦合式、磁共振耦合式、电磁波辐射式三种模式。
电磁感应耦合式是利用可分离变压器的感应耦合作用实现无接触电能传输，传输距离为mm级，优势是传输功率大，劣势是变压器损耗大，传输距离过短，传输效率随传输距离的增大迅速减小，适用于交通运输、冶金矿山、水下作业。
电磁波辐射式是将电能转换成微波，通过空间传播到接收端实现无线电能传输，传输距离为km级，优点是传输距离远，缺点是发射接收天线设计要求高，能量定向传输，传输效率不高，适用于空间太阳能电站、卫星供电。
