Abstract

We considered about a wireless power transfer for breaking inconvenience of wiring power sources. The best way how to supply electric power through wireless system is using the electromagnetic coupled resonance phenomena. It can be supplied the electric power to the load. It is analyzed the transfer characteristics through the basic experiment with variable LED load. And we could apply protection circuit to find the accurate resonance point that can get the high efficiency result of wireless power transfer.
