| 摘 要： | 基于电磁谐振技术,设计了一种以电磁波为载体,实现能量无线传输的系统。利用直径为30cm、间距为2mm的两个铜线圈间的耦合作用,分别使用毕奥-萨伐尔定律和法拉第电磁感应定律对发射线圈和接收线圈进行定量和实验分析。结果表明:当发射源功率仅为0.635mW时,系统的最远传输距离达到631.5cm,传输效率为20.4%。

| Abstract: | ls, which the diameter is 30cm and the spacing is 2mm, we have realized the power wireless transmission. Using the Biot-Savart Law and the Faraday Law of electromagnetic induction, we carry on the quantitative analysis and experiment to the transmitting coil and the receiving coil. The result indicated: when the transmitting power is 0.635mw, the farthest transmitting range achieves 631.5cm and the transmission efficiency is 20.4%. |
