非接触式电能传输综述

Overview of Contactless Power Transmission

非接触式电能传输是一种利用电磁感应耦合技术、电力电子技术和现代控制技术实现的电源侧与负载侧完全分离的电能传输技术，它克服了传统电能传输方式在一些特殊环境如易燃、易爆、水下等场合存在的弊端，实现了电能安全可靠地传送。文中简单介绍了非接触式电能传输的工作原理和方式，归纳总结了电磁感应式、电磁共振式及辐射式三种不同传输方式的特点，分析了该技术的应用前景。

Contactless power transmission makes use ofelectromagnetic induction coupling technology, power electronic technology and modern control technology to realize the separation between the power side and the load side in power transmission. It overcame the shortcoming of traditional power transmission mode and realized the power transmission safely and reliably in some special environments such as flammable, explosive and underwater ones. This article simply introduces the principle and method of contactless power transmission, and summarizes the characteristics of three different transmission modes including electromagnetic induction, magnetic resonance and radial types. And its application prospect is also analyzed.
