可分离变压器实现的非接触电能传输系统研究

Contactless Power Transfer System Using Isolation Transformer

传统电能传输主要通过导线直接接触进行,在一般环境下这种方式合理有效,被广泛采用。但在一些特殊环境,如易燃易爆场合和水下系统,这种电能传输方式的安全性难以得到保证。非接触电能传输系统利用电磁感应耦合技术与电力电子技术,避免了传统电能传输方式裸露导体的存在和接触火花的产生,实现了电能的安全传输。研究了一种采用可分离变压器传输能量的非接触电能传输系统。通过分析可分离变压器的工作特性,得出影响传输功率的几个因素,并给出了采用串联谐振式逆变器和可分离变压器优化绕法的实验结果。

Most electrical equipments get the energy through plugs from source, this kind of energy transmission sys-tem is efficient and accepted widely. But it is unsafe at the special circumstance such as undersea applications and flammable environments. This paper describes a contactless power transmission system using isolation transformer, which is spark free and no uncovered conduct being exposed to the environments. This paper finds several factors which affect the power transfer ability of the contactless system through isolating transformer analysis. An experiment result is given at the end of this paper.
