Abstract:

This paper first analyzes the current commercialization situation, the formulation of product standards, the publication status of academic papers and patents of wireless power transmission technology at home and abroad. Then, it discusses the existing problems of the two types of most popular wireless power transmission technologies, i. e. inductively coupled wireless power transmission and magnetically coupled resonant wireless power transmission, and then puts forward their differences in principle, structure and characteristics, which is aimed to resolve the confusion of inductively coupled and magnetically coupled resonant wireless power transmission technologies to promote the further development of wireless power transmission technology. Finally, based on the bottleneck of the development of existing wireless power transmission technology, two new types of wireless power transmission technologies are introduced based on the fractional-order circuit theory and parity-time-symmetric theory. It is pointed out that a fundamental breakthrough in mechanism is important for the wireless power transmission technology to become a general technology.
