Abstract :
Electromagnetic Wireless Power Transmission (WPT) can be realized by using resonant coils coupled via their magnetic fields; in order to extend the range for power transmission, it is convenient to introduce additional relay elements. By considering a simple, yet rigorous, equivalent network, we derive a general property which is useful for the design of wireless power transfer networks with relay elements. A test system is designed, simulated and measured to show the validity of the proposed procedure.
