【摘要】：无接触电能传输技术较好地克服了传统导线传输技术的弊端,提高了电能传输的安全性和便利性,尤其适合于一些极端特殊的用电环境,因而具有广阔的工程应用前景。当前,无接触传能技术可划分为三种类型,分别是电磁感应式无接触传能技术、微波辐射式无接触传能技术以及谐振磁耦合式无接触传能技术(witricity)。其中由美国麻省理工学院教授于2006年提出的谐振耦合式无接触传能技术代表了当前无接触电能传输的最新发展方向,具有另外两种技术所不具备的诸多优点,是未来无接触传能技术发展的重要方向。因此,谐振耦合式无接触传能技术是目前国内外研究的热点课题之一,相关研究已经取得了很大进展。但在一些关键问题上依然存在不足和空白,尤其在实际应用方面尚需进一步的探索。本文根据谐振耦合式无接触电能传输的原理,在综合现有研究成果的基础之上,对无接触电能传输技术进行了较为深入地研究和开发。提出了无接触电能传输线圈的等效电路模型,并根据等效电路模型,提出了分布参数计算方法。利用matlab计算软件对等效电路进行特性进行了分析和计算,获得了线圈的阻抗特性曲线,从而确定了谐振线圈的谐振频率,为无接触电能传输线圈设计提供了计算方法和理论基础。在上述工作的基础上,本文进一步在无接触传能技术工程化方面进行了探索和研究。首先,考虑到在实际应用时线圈位置的变动性和不确定性,设计了线圈智能控制系统,使无接触传能线圈能实时调整线圈的物理状态,以保证系统随时保持在最佳工作状态。然后,设计了微型无线充电系统,为无接触电能传输技术的开发工作奠定了基础。
[Abstract]:Contactless power transmission technology has overcome the disadvantages of traditional traverse transmission technology, improved the security and convenience of power transmission, especially suitable for some extremely special electricity environment, so it has a broad engineering application prospect. At present, contactless energy transfer technology can be divided into three types, namely electromagnetic induction non-contact energy transfer technology, microwave radiation non-contact energy transfer technology and resonant magnetic coupling non-contact energy transfer technology (witricity). The resonant coupled contactless energy transfer technology, which was proposed by MIT professor in 2006, represents the latest development direction of contactless power transmission, and has many advantages that the other two technologies do not have. It is an important direction for the development of contactless energy transfer technology in the future. Therefore, resonant coupled contactless energy transfer technology is one of the hot topics at home and abroad, and great progress has been made. However, there are still shortcomings and gaps in some key issues, especially in practical applications. Based on the principle of resonant coupled contactless power transmission and on the basis of existing research results, the contactless power transmission technology is deeply studied and developed in this paper. The equivalent circuit model of contactless electric power transmission coil is presented. According to the equivalent circuit model, the calculation method of distribution parameters is proposed. The characteristic of equivalent circuit is analyzed and calculated by using matlab software. The impedance characteristic curve of the coil is obtained, and the resonant frequency of the resonant coil is determined. The calculation method and theoretical basis are provided for the design of contactless electric power transmission coil. On the basis of the above work, the engineering of contactless energy transfer technology is further explored and studied in this paper. Firstly, considering the variation and uncertainty of coil position in practical application, a coil intelligent control system is designed to make the contactless energy transfer coil adjust the physical state of the coil in real time, so that the system can be kept in the best working state at any time. Then, the micro wireless charging system is designed, which lays a foundation for the development of contactless power transmission technology.
