Theoretical analysis on maximum efficiency of multiple-transmitter inductive power transfer system
Hiroto Kawabata, Duong Quang Thang, Minoru Okada (naist) WPT2016-59
Abstract (in Japanese) (See Japanese page) 
(in English) This study investigates the maximum power transfer efficiency (RF–to–RF efficiency) of inductive power transfer (IPT) system using an arbitrary number of transmitters under an assumption that there is significant cross-coupling among transmitters. We model the system by Z-parameter and derive the maximum efficiency, the optimum load impedance and input currents based on the first order necessary condition. We confirm the validity of analytical solution by electromagnetic field simulation on IPT systems with 4 transmitters.
