随着科技的发展，无线电技术越来越广泛应用到生活中。文章采用电磁感应式手机充电原理，在发送和接收端各有一个感应线圈，发送端连接有线电源，通过振荡电路使得发送线圈产生振荡电磁波信号，接收端线圈感受该信号，经过整流滤波电路，将振荡信号变成直流量，进行电池的充电。同时采用CN3068芯片，设计了电流充电的监控电路，使用MSP430G2553超低功耗单片机作为无线充电系统的检测控制核心，电能充满后给出充满提示且自动停止充电。%With the development of science and technology, wireless technology is more and more widely used to the life. Based on the principle of electromagnetic induction type mobile phone charging, the sending and receiving end each have an induction coil, the sender connection cable power supply, through the oscillation circuit oscillation caused the sending coil electromagnetic wave signal, the receiver coil feelings of the signal, after rectification filter circuit, the oscillation signal into a straight flow, in charge of the battery.Adopt CN3068 chip at the same time, the design of the charging current monitoring circuit, use MSP430G2553 ultra-low power MCU as the core, the detection and control of wireless charging system electricity given after full of full of hints and automatically stops charging.
