The application status and key problems of wireless power transfer technology in daily life

With the continuous development of science and technology, the traditional wired power transfer technology can no longer meet the needs of further daily use, so wireless power transfer technology has been developed accordingly in a way. This paper first introduced three major types of wireless power transfer technology, such as radiation, magnetic field coupling, and electric field coupling, and then the paper introduced their advantages, disadvantages, and some basic principles. The paper also analyzed the present application of wireless power transfer technology in the field of transportation and home furnishing. By using Multism and Matlab/Simulink, the paper also simulated the classical model of a magnetically coupled resonance wireless power transfer (MRPT) system, through which the paper summarized some key problems about efficiency and safety, which need to be solved urgently for further development in the future, and finally the paper came up with some new ideas for figuring the key problems.
