Design of Efficient Wireless Power Transfer via Magnetic Resonant Coupling using Multiple Transmitter Coils
Hiroki Narita, Takafumi Koseki (Univ. Tokyo) WPT2015-26
Abstract (in Japanese) (See Japanese page) 
(in English) Wireless Power Transfer (WPT) is expected as a novel power feeding method where conventional wiring is difficult or causes problems.
In case of Longitudinal WPT such as dynamic WPT, if transmitter coil is single and long type, there is high frequency current even if there is no receiver coil.
However, this case is not proper in the view point of transfer efficiency improvement and electromagnetic compatibility.
Also multiple transmitter with individual power source can reduce rated value of transmitter.
In this paper, requirement of transmitters voltage for maximizing efficiency and control method for realization of maximum efficiency using voltage/current of transmitters are discussed and confirmed by numerical simulation.
