Other AbstractWireless power transfer technology refers to the use of space intangible medium (electric field, magnetic field, electromagnetic wave, laser, ultrasonic, etc.) to achieve the power transfer between the power source and electrical equipment,which is an ideal way of power supply, and has a broad application prospect in the medical implanted devices, robotics, wireless sensors and various kinds of electrical equipment. However, the conflict between the transfer distance and transfer efficiency is the biggest obstacles restricting the further commercialization of the technology. In recent years, magnetic coupling resonant wireless power transfer technology is a new kind of technology. Compared with the relatively mature technology, such as microwave, laser, inductive coupling etc, magnetic coupling resonant has shown potential application in the field of electrical equipment used in daily lives, because of moderate transfer distance, high transfer efficiency, and low radiation loss. Nevertheless, at present, the research of the technology is insufficient to meet practical demands, especially in a particular range, the magnetic coupling resonant wireless power transfer system is inefficiency, which need to targeted propose solutions to improve practicability of the system; At the same time, the system parameters show more complex coupling relationship in the design since the two additional groups of coils has been introduced. The lack of the constraint relationship among the parameters and design principles, a detailed analysis on the parameters of the coupling relationship is needed, and the system design flow and constraint relation in the design stage should be clear, which can provide theoretical basis for system design. In response to the above problems, based on the theoretical analysis, FEM (Finite Element Method) and experimental measurement, this paper focuses on the system model, the critical coupling state, design constraints and transfer characteristics and so on.
