水下景觀燈無線供電系統(tǒng)研制
[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.
