Abstract :
The maximum transfer efficiency of WPT system with resonant transmitting/receiving elements and non-resonant transmitting/receiving elements has been analyzed and compared in this paper. It has been observed that the resonant characteristic of transmitting/receiving elements gives little impact on the maximum transfer efficiency when the receiving element is close to the transmitting element, but affects the maximum transfer efficiency greatly when the receiving element is far from the transmitting element.
