簡(jiǎn)易無(wú)線供電系統(tǒng)設(shè)計(jì)

無(wú)線供電是一種方便安全的新技術(shù)，無(wú)需任何物理上的連接，電能可以近距離無(wú)接觸
地傳輸給負(fù)載。本文根據(jù)電磁感應(yīng)原理，設(shè)計(jì)了一種簡(jiǎn)易的無(wú)線供電原型，并對(duì)其進(jìn)行了一個(gè)初步的分析和探討。該系統(tǒng)相當(dāng)于一個(gè)分離式疏松耦合變壓器，選用Ferrite 芯增加其耦合效率、減少漏磁。

Design of A Simple Wireless Powering System XIA ,Zenglin CHEN,Qijun Department of Control Science and Engineering, Tongji University, Shanghai 200092, P.R.China Abstract: Wireless powering system is a new technique, which is convenient and safe. Power energy can be transferred to the load without any physical connections. Based on electromagnetic coupling, this paper presents a simple wireless powering prototype, as well as its primary analysis and discussion. It works like a loosely coupled transformer whose primary side and secondary side are detachable. Ferrite pot core is used to improve the coupling efficiency and reduce the magnetic leakage.
