摘要
随着电子和无线电技术的不断发展,电子数码产品越来越丰富。随之而来的是,人们对产品便携充电的要求越来越迫切。本文介绍了无线电能传输的基本原理,利用变压器线圈和有源晶振,设计了一种便携的无线充电器,简单实用,成本低廉,经验证能够实现实用价值。
With the continuous development of electronics and radio engineering, electronic digital products have become increasingly diverse. Followed by people＇s requirements of the product＇s portable charging have become more and more urgent. This paper introduces the basic principles of wireless power transmission, and designs a portable wireless charger by using transformer coil and active crystals. This charger is simple and practical, with low cost, and the experiences show that it can achieve practical value.
