Abstract Wireless power transmission technology is the emerging power transfer mode and has wide applied prospects. Currently, inductive coupling power transmission (ICPT) and resonant coupling wireless power transmission have been received extensive attention. Based on electromagnetic induction principle, low frequency, low transmission distance and high efficiency are the characteristic of ICPT. On the other hand, transfer power in middle range distance with high efficiency is achieved by resonant coupling method. Moreover, spatial location and obstructions is not influenced the resonant coupling method, but its frequency is in MHz range. In this paper, the difference between these two wireless power transmission technologies in principle models and applications is compared and the key problems of the technologies is analyzed, which can supply the references for the design and application of these two wireless power transmission.
