|
摘要
磁共振式无线电能传输方式具有传输功率高、距离远和无需对准等突出优点,和传统的电磁感应式相比有更加广泛的应用前景。本文通过建立双接收端磁共振式无线电能传输系统的等效电路模型,根据电路理论推导出系统中各回路的电流表达式,从而求出功率、效率的表达式。其次,运用Maxwell有限元分析软件建立了双接收端线圈的3D模型,并且建立外电路进行联合仿真,得出发射线圈和接收线圈的电流、电压和功率的值。仿真结果表明多接收端模型中两个平行放置的接收线圈之间的影响可以忽略不计,并且系统存在最佳的工作距离和负载电阻。
The magnetic resonance wireless power transmissionmodehas the advantages of high transmission power, long distance and no need for alignment. It has wider application prospects than the electromagneticinduction mode. In this paper, we established the equivalent circuit model of the dualreceiver magnetic resonance wireless power transmission system, we derived the current, power and efficiency expressions of loops according to the circuit theory. Secondly, Maxwell finite element software is used to establish the 3 D model of the coils, co-simulation of model and external circuit to obtain the values of current, voltage and power of the transmitting coil and the receiving coils.The results show that the effect between two parallel receiving coils in the multi-receiver model is negligible and the system has an optimum working distance and load resistance.
