Ringhõljundusvõrk

Ringhõljundusvõrk, also known as a resonant inductive coupling network, is a system designed for wireless power transfer over a moderate distance. It typically consists of multiple resonant coils strategically placed to create a magnetic field that can efficiently transfer energy between a transmitter and one or more receivers. The principle of operation relies on the phenomenon of resonance, where the transmitter and receiver coils are tuned to the same resonant frequency. This tuning maximizes the energy transfer efficiency by creating a strong magnetic coupling between the coils.

The network is formed by arranging these resonant coils in a specific configuration, allowing power to be transferred not just directly between two points, but potentially between multiple points within the network. This creates a flexible power delivery system where devices can receive power without a direct line of sight to the transmitter, as long as they are within the range of the magnetic field generated by the network. Applications for ringhõljundusvõrk include charging multiple electronic devices simultaneously, powering sensors in hard-to-reach areas, and potentially creating wireless charging zones in homes or public spaces. The efficiency of the transfer is dependent on factors such as the distance between coils, their size and alignment, and the quality factor of the resonant circuits. Research in this area focuses on improving efficiency, increasing transfer distance, and ensuring safety for users.
