[Abstract]:As a kind of advanced non-contact power supply technology, the magnetically coupled resonant wireless power supply technology not only overcomes the limitation of wired power transmission, but also overcomes the inherent shortcomings of inductive and radiative wireless power supply. It has become a hot research topic at present. The magnetic coupling resonance wireless power supply system mainly relies on the magnetic coupling between the coils to transmit the electric energy. It does not involve any wire connection in the transmission process, so it can avoid the interference of the external environment factors. Compared with other transmission modes, it has obvious advantages in transmission characteristics, and can better realize the popularization and application of wireless power supply technology. This paper mainly studies the basic principle and transmission characteristics of the magnetic coupling resonance wireless power supply system, and establishes four basic topologies of the magnetic coupling resonance wireless power supply system through the basic principle. The transmission efficiency of the system under four basic structures is analyzed theoretically. At the same time, the effects of coupling coefficient, loss coefficient, quality factor and frequency on the transmission characteristics of the system are analyzed. The relationship between the parameters and the transmission efficiency is simulated by matlab simulation software, and the relationship between the parameters and the transmission efficiency is obtained. Through the study of these characteristics, the coupled mode analysis of the magnetically coupled resonant power supply system with the addition of relay coils is carried out, and it is obtained theoretically that the transmission distance and transmission efficiency of the system can be effectively improved by adding the trunk coil. It can improve the transmission characteristics of the system. According to the analysis and research, the components and modules needed for the system design are determined, the hardware of the system is built, the output voltage of each module before and after adding the trunk coil, the transmission efficiency of the system and the distance between the coils are tested. Finally, the analysis of test results proves the feasibility of designing the system and the increase of transmission distance and efficiency after adding trunk coil.
