摘 要

传统的导线接触式电能传输模式已经不能满足生产和生活的要求，人们迫切地需要一种新型的电能传输方式来满足新型电气设备及各种特殊条件下的供电需求。

本设计中我们利用电磁感应原理设计出非接触式电能传输系统。在发射端由单片机产生占空比可调的PWM信号，通过发射线圈将信号无线传输至接受线圈，并点亮接收端的LED灯。并利用谐振耦合使系统功率最大化。

非接触式电能传输技术打破了部分特殊行业中的环境限制，并提高了移动设备传输电能的安全性。因此在水下作业，矿井采掘，航空航天，医疗器械，机器人，便携式电子设备等场合有着广泛的应用前景。

The Design of Non-contact Power Transmission System Based on Electromagnetic Induction Principle

Abstract

The traditional wire contact electrical energy transmission mode can not meet the production and living requirements, people urgently need a new type of power transmission to meet the new electrical equipment and various special conditions of power supply.

In this design, we use the principle of electromagnetic induction to design a non-contact power transmission system. At the transmitter, the PWM signal is generated by the MCU, and the signal is transmitted to the receiving coil through the transmitting coil, and the led lamp at the receiving end is illuminated. And the system power is maximized by resonant coupling.

Non-contact power transfer technology breaks the environmental limit in some special industries, and improves the safety of power transmission of mobile devices. Therefore, in underwater operation, mining, aerospace, medical devices, robots, portable electronic equipment and other occasions have a wide range of application prospects.

Keywords:non-contact transmission;SCM; PWM signal; resonant coupling
