Software Design And Experimental Verification Of Wireless Power Transmission Based On Magnetic Coupling Resonant

With the development of industries and technology, people have more demand for wireless power transmission. Power wireless transmission technology is that electrical equipment get electricity from the power grid via a non-contact method. Compared with traditional wired power supply, it is safer and more convenient.Magnetic coupling resonant wireless power transmission is a new type of power transmission technology in recent years, compared with the electromagnetic wave transmission mode, which has the advantage through the obstacle; compared with the transmission mode of electromagnetic induction, which has the advantages of further transmission distance.In this paper, the principle of resonant magnetic coupling wireless power transmission system was firstly analyzed, it can be known that the transmission range of the system is mainly drawn in near field. Two coil of system in the same self-resonant frequency exchange energy through constant magnetic field to achieve wireless power transmission.Magnetic coupling resonant wireless power transmission system was studied, analyzed working principle, the structure, the energy transfer process and this process should follow the standards of the system; mathematical model of the system was established of magnetic coupling resonant wireless power transmission, respectively, based on the coupled-mode theory and circuit theory. On the basis of the model factors affecting the system was analyzed and critical conditions of optimization system transmission characteristics was proposed.Magnetic coupling resonant wireless power transmission system design projects was put forward based on specific load impedance, specify the transmission distance and transmission power according to system characteristics research. Based on Matlab and Labview software programs of design were written, which can input load power, transmission distance, load resistance, and can output the proposed transmission system parameters: supply voltage, coil size, resonant frequency, etc; and the results were verified by experiment. Finally, software of load power and transmission efficiency are both high were design after analyzing the data of experimental results and optimizing constantly the software, which provide a theoretical basis for further research in this field.
