Wireless energy transmission average power

Wireless power transmission system for medium size applications

A research team from the Department of Electrical and Electronic Engineering at the University of Hong Kong (HKU) "recently developed a new concept of wireless power supply system called" domino-resonator "for medium-sized applications (transfer of wireless energy over a distance of the order of magnitude equivalent to the size of the resonator). The study shows that electrical energy can be transmitted through several resonators arranged in the form of a right, circular or "domino". still shaped like a “Y.” This notably means that the direction of the energy flow can be controlled and even divided into several branches.

The researchers found that the maximum efficiency frequency deviated from the resonant frequency of the resonator due to cross coupling which affects the average flow of the energy flow. Nikola Tesla had shown that the optimal operating frequency corresponds to the resonant frequency for a pair of resonators. The research team showed that it would move away from it if more than two resonators were used. Researchers have also developed new techniques to control the flow of energy in "domino-resonator".

These new wireless power systems provide new ways to transfer power without using continuous cables over several meters. It is an emerging technology that transmits energy in a very flexible way. Further research is being conducted by the HKU team to improve transmission distances and efficiency.

No numbers?

Ah there, it depends on the amperage and everything ... But it opens the possibility of possibly recharging an electric vehicle while driving, right?
