Development of WPT technology with magnetic coupling resonance and its application

Wireless power transmission with magnetic coupling resonance is a technology that integrates with the application of multidisciplinary of electromagnetic field, high frequency power electronic technology, electro-magnetic induction, magnetic materials, etc. which can realize the electrical power transmission in middle dis-tance safely, efficiently and flexibly. This paper points out that the wireless power transmission with magnetic cou-pling resonance is a new type of technology that is made for the current technology development of integration with multidisciplinary and has broad application prospects, on the basis of types of wireless power transmission and its prospect of development and application, and sums up the present developmental level of wireless power transmission with magnetic coupling resonance and its hot issues. And the author puts forward the challenge for the power electronic technology and some critical issues that need to be studied for adapting to the high frequency converter technology, from the prospective of improving transmission efficiency, reducing the size of transmitting and receiving coils.
