Maximum Transmitting Efficiency of Wireless Power TransferSystem with Resonant/Non-resonant Transmitting/ReceivingElements

摘要

Wireless power transfer (WPT) is interested again because of its potential appli-cation to charge laptops, cell-phones, household robots, MP3 players and other portable electronics without cords [1]-[2]. The optimum load for maximum transfer efficiency of WPT system was presented when the WPT system was equivalent to a 2-ports lossy network in [3] by present authors. The maximum transfer efficiency of WPT system with resonant transmitting/receiving elements and non-resonant transmitting/receiving elements will be further analyzed and compared in this pa-per to investigate how the resonant characteristic of transmitting/receiving elements affects the transfer efficiency of a WPT system.
