Abstract :
In this paper, a comparative analysis was studied on the big air-gap for contact-less power transfer technology, and an electromagnetic resonant coupling mode which is easily realized was extracted. Author proposed an appropriate compensation method to improve the transmission efficiency. The optimal way adopted in the paper is easy to implement. It also provided a reliable basis for the project implementation.
