A Novel Analysis of A Multi-Resonant ZVS Wireless Power Transfer System Using Electromagnetic Field Resonant Coupling Resonators

Abstract (in Japanese) (See Japanese page) 
(in English) A novel multi-resonant ZVS wireless power transfer system using electromagnetic field resonant coupling resonators is presented. I propose 3 analytical techniques to analyze the coupling resonant circuit in electromagnetic field systematically. The first is the analysis by use of 2-dimensional space multi-resonant circuit that is modeled on the behavior of the electromagnetic field in 4-dimensional space time. The second is the harmonic resonance analysis (HRA), the third is F-parameter resonance analysis (FRA). I clarify that power efficiency and transfer efficiency differ in each characteristics. I show that in the simulation the transmission power of above 450W at 0.4m can be got and high efficiency of 81.5% and power of 81.6W at 10.50MHz is achieved by utilization of ZVS operation technique.
