Abstract:

In this report, we present a technology to realize flexible and mobile wireless power transfer, which is based on the coupling of an array of resonators. Near-field wireless power transfer using resonant coupling has been shown to be a promising technology for many applications. However, the mobility of device while operating is limited to the near-range of the transmitter. We show that, by using an array of resonators, the range of efficient power transfer can be largely extended. More importantly, this new technology can provide wireless power to both static and mobile devices. The principle of this technology will be explained in this paper. Analytical and numerical models will be used to evaluate the performance of a wireless power transfer system with an array of resonators. Advantages and potential applications of the technology will also be discussed.
