【摘要】：随着人们思想意识、生活方式的不断改变,人们对于城市生活质量的要求越来越高,传统的单功能路灯已不能满足人们的需求。景观照明以其独特的艺术魅力正在吸引大众的目光,并越来越受到人们的青睐。目前,水下景观灯普遍采用线缆供电方式,由于其所处环境恶劣,该供电方式必然会限制水下灯的防护强度,产生供电安全隐患、布线施工困难以及后期维护麻烦等不可避免的缺点。电磁感应耦合能量传输(Inductive Coupled Power Transfer,ICPT)技术能够通过空间磁场耦合的方式实现电能从静止电网向用电设备的非接触传输,从而解决了传统供电方式存在的上述问题,迎合了人们对日常生活中的电气设备安全高效性、灵活性和智能化的需求,为景观灯的研究和发展开拓了一种新思路。ICPT基于法拉第电磁感应原理,综合利用电力电子能量变换技术、磁场耦合技术以及现代控制理论和方法等,以其原理简单、容易实现、近距离传输效率高、传输功率大等特点,越来越受到工业界和学术界的广泛关注,成为研究热点。因此本文主要基于ICPT技术原理和控制方法,研究适用于中小功率等级ICPT系统的设计流程和方案,并研制出一款100W的无线供电系统,实现电能的非接触传输。在研究过程中,作者主要做了以下工作:(1)对ICPT系统的基本结构和原理做了简要介绍,分析了该无线供电系统的技术需求,确定了系统的电路结构。(2)分析对比了几种高频逆变电路、谐振网络模型、整流滤波电路以及稳压电路的优缺点和适用情况,设计了系统的主电路。(3)设计出系统的耦合机构,用mathcad软件建立了系统的数学公式,计算出系统工作时的电路参数,并研究了系统的电路参数设计和器件选型。(4)设计了系统保护电路、驱动电路、控制电路等辅助电路。(5)用simulink软件仿真出系统的控制效果,并搭建实验平台对系统进行了功能性验证。
[Abstract]:With the constant change of people's ideology and life style, the demand for the quality of urban life is getting higher and higher. The traditional single-function street lamp can not meet the needs of people. Landscape lighting with its unique artistic charm is attracting the attention of the public, and more people favor. At present, underwater view lights generally use cable power supply mode. Because of their harsh environment, this power supply mode will inevitably limit the protection intensity of underwater lights and produce hidden trouble of power supply safety. Difficult wiring construction and late maintenance trouble and other inevitable shortcomings. Electromagnetic induction coupled energy transmission (Inductive Coupled Power Transfer,ICPT) technology can realize the non-contact transmission of electric energy from static power grid to electrical equipment by means of space magnetic field coupling, thus solving the above problems existing in the traditional power supply mode. It caters to the demand for safety, efficiency, flexibility and intelligence of electrical equipment in daily life, and opens up a new way of thinking for the research and development of view lights. ICPT is based on Faraday electromagnetic induction principle. The power electronic energy conversion technology, magnetic field coupling technology and modern control theory and methods are synthetically utilized. It is characterized by its simple principle, easy realization, high transmission efficiency and high transmission power. It has attracted more and more attention from industry and academia and has become a research hotspot. Therefore, based on the principle and control method of ICPT, this paper studies the design flow and scheme of ICPT system suitable for medium and small power level, and develops a 100W wireless power supply system to realize the non-contact transmission of electric energy. In the course of the research, the author mainly does the following work: (1) the basic structure and principle of ICPT system are briefly introduced, and the technical requirements of the wireless power supply system are analyzed. The circuit structure of the system is determined. (2) the advantages and disadvantages of several high frequency inverter circuits, resonant network models, rectifier filter circuits and voltage stabilizing circuits are analyzed and compared. The main circuit of the system is designed. (3) the coupling mechanism of the system is designed, the mathematical formula of the system is established by using mathcad software, and the circuit parameters of the system are calculated. The circuit parameter design and device selection of the system are also studied. (4) the auxiliary circuits such as system protection circuit, drive circuit, control circuit and so on are designed. (5) the control effect of the system is simulated with simulink software. An experimental platform was built to verify the functionality of the system.
