摘要
随着科技水平的不断发展与进步,手机、平板电脑以及笔记本等电子设备的更新速度越来越快,能量来源也是其发展过程中很重要的一部分,传统充电方式的缺点也更加明显,这种充电方式已逐渐被人们所摒弃,所需要的就是一种可应用于电子设备的无线充电技术。设计了一种基于磁耦合谐振原理的无线充电技术,包括变压、整流滤波、稳压、PWM、发射和接收6个部分,实现了能够在几厘米的范围内进行电能传输并获得比较稳定的电压,具有能量传输效果好、成本低、实现简单、安全可靠、适用对象广等特点。
With the development of technology, the renewal speed of mobile phone, PC and computer is getting faster and faster. The energy source also plays an important role in this process. The disadvantages of traditional charging mode have been more and more obvious and this mode has been discharged by us. What we need is a wireless charging technology which can be used by electronic devices. This paper designs a wireless charging system based on magnetic coupling resonance, including transformer, rectification, voltage stabilization, PWM, emission, receipt. The system can achieve electric energy transmission in several centimeters and gain a stable voltage, which has the advantages of better effect of energy transmission, low cost, easily realized, safe and broad applied targets.
