About awarded research〉
Kentaro Matsuura, Daisuke Kobuchi, Yoshiaki Narusue, and Hiroyuki Morikawa, "Communication-Less Receiver-Side Resonant Frequency Tuning for Wireless Power Transfer Using Magnetic Resonant Coupling, " IEICE Technical Report, WPT2020-26, Dec. 2020.
Magnetic resonant coupling wireless power transfer is expected to be applied to recharge electric vehicles and mobile devices since it can provide highly efficient power over a transmission distance of up to approximately 1 meter. However, the presence of metal, water, etc. in the vicinity of the power receiver causes the resonance frequency of the power receiver to change, resulting in a decrease in the efficiency of wireless power transfer. In this study, we have developed a communication-less receiver-side resonant frequency tuning mechanism that cancels out the effects of resonant frequency fluctuations using a variable reactor composed of purely electronic components. We have realized a wireless power transfer system that enables highly efficient and stable power transfer even under less than ideal operating conditions.

〈Your impression & future plan〉
I am very pleased to receive this honorable award. For the widespread use of wireless power transfer systems, I believe that it is necessary to enable stable power transfer in any environment. In the future, I would like to demonstrate the effectiveness of our proposed method in applications that are more in line with actual settings.
