英文摘要： The convenience and safety of power supply of home appliances has been widely concerned. The project aims at studying a low-cost, high-efficiency and high-quality wireless power supply solution to home appliances to achieve the optimal operation of a variety of consumer electronics devices on a common energy launch platform. For the transmission efficiency and power quality problems, a wireless power transfer mode will be proposed based on an improved envelope modulation mechanism. For the energy efficiency optimization control problem of a variety of loads on the universal launching platform, a segmented optimal frequency dynamic tracking method will be proposed. For the identification of load validity, a signal interactive method based on the energy channel will be proposed. For the optimal control problem, a dynamic load identification method based on impedance scanning will be proposed. For system optimization and characteristic analysis, a system-wide, multi-physics mixed-modeling method will be proposed. The solution of the above key issues will lay the foundation for the development and application of home appliances wireless power transfer technology, and enriches the theory of wireless power transmission technology.
