基于电能谐振磁耦合无线供电的无线鼠标的设计与实施

Design and Implementation for Wireless Mouse of Wireless Power Supply Based on Electromagnetism Resonance Coupling

本文利用电能的谐振磁耦合传输原理,设计了一种电能无线传输的电路,给无线鼠标提供工作电源。装置包括发射部分和接收部分,从计算机USB取电,通过高频逆变电路,将直流电转换为高频交流电,通过发射线圈发射出去。接收线圈接收电能,整流滤波后为鼠标供电。

Using the principle of the electric energy of the electromagnetism resonance coupling transmission, a kind of electric power wireless transmission circuit is designed. The device comprises emission and receiving part. Electric energy is taken from the computer USB, and through the high frequency inverter circuit, converts direct current （dc） to high frequency alternating current, transmitting coil launch out. The receive coil receiving power, and rectifier filter, supplies power to the mouse.
