Kentaro Matsuura (D2), Department of Electrical Engineering and Information Systems, received Student Best Paper Award at 2021 Asian Wireless Power Transfer Workshop

 

On 12th December 2021, Kentaro Matsuura (D2), Department of Electrical Engineering and Information Systems, received Student Best Paper Award (1st Best Paper Award + WiPoT Award) at 2021 Asian Wireless Power Transfer Workshop(AWPT2021)



Student Best Paper Award (1st Best Paper Award + WiPoT Award)
This award is presented to the author of the most outstanding research result among the papers at AWPT2021 whose first author is a student.

About awarded research
"Experimental Validation of Communication-Less Receiver-Side Resonant Frequency Tuning for Magnetic Resonant Wireless Power Transfer Systems"
Magnetic resonant 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 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 power transfer efficiency. In this study, we proposed a mechanism that automatically corrects the resonant frequency at the receiver side without using wireless communication with the transmitter and experimentally demonstrated that power transmission with high transmission efficiency is possible even under the influence of the surrounding environment.

Your impression & future plan
I am very honored to receive this award. I believe that it is essential to build a system that is easy for users to use in order to spread the use of wireless power transfer systems. In the future, I would like to implement the proposed method in various wireless power transfer devices, conduct evaluations, and demonstrate its effectiveness.
