Thévenin Equivalent Circuits for Magnetisc Coupling Resonators (Series–Series, Series– Parallel) in Wireless Power Transfer Systems

In this paper the equivalent Thévenin circuits for two connections (series-series (ss), series-parallel (sp)) are obtained, for the magnetic coupling coils (resonators), used in wireless active power transfer. Based on the maximum active power transfer theorem, the optimal load parameters (connected to the terminals of the receiver coil) will be determined so that it receives maximum active power.
