[Abstract]:Compared with the traditional power transmission mode, radio energy transmission technology has many advantages, such as can avoid wire wear, aging, ensure power supply safety; The electromagnetic coupling resonance radio energy transmission, as the most potential radio energy transmission technology, has moderate transmission distance and high transmission efficiency. Small harm to the environment and human body and other advantages, attracting a large number of researchers into it. At present, the electromagnetic coupling resonant radio transmission has some research results, but most of them are in the stage of theoretical research and basic experiment, but no concrete application products have been seen. The electromagnetic coupling resonant radio energy transmission technology is studied, including system transmission characteristic analysis and hardware design. The feasibility of applying this technology to wireless mouse is verified, which provides a certain basis for the concrete application of this technology. In this paper, three kinds of radio energy transmission technologies are introduced, and the research status of electromagnetic coupled resonance radio energy transmission is described. Based on coupling mode theory and circuit theory, the analysis model of radio energy transmission system is established. The expressions of output power and transmission efficiency of the system are obtained by theoretical calculation. The effects of resonant frequency, load resistance, coupling coefficient and internal resistance of the loop on the transmission characteristics of the system are analyzed in detail by Matlab and Pspice simulation. It provides a theoretical basis for the overall design of radio energy transmission system. Secondly, the whole hardware design of radio energy transmission system is completed, including class E inverter module design, resonant coil design and rectifier voltage regulation module design. The whole radio energy transmission system is analyzed according to Pspice simulation, and the correctness of the design is verified. Finally, on the basis of the hardware design of the system, the transmission characteristics of the radio energy transmission system are verified by experiments, and the experimental results are in good agreement with the theoretical analysis. The feasibility of applying electromagnetic coupling resonant radio energy transmission technology to wireless mouse is discussed. When the resonant frequency is 1.5 MHz and the coil diameter is 10cm, the radio energy transmission distance is 30 cm, and the transmission distance is 3 times the coil diameter. It shows that the electromagnetic coupling resonant wireless transmission mouse can be realized to a great extent.
