Study of resonator optimization in a WPT system Yuichi SAWAHARA1 Toshio ISHIZAKI2 Ikuo AWAI3

Faculty of Science & Technology, Ryukoku Univ., 1-5 Yokotani, Seta Oe-cho, Otsu, Shiga Pref. 520-2194 Japan E-mail: 1 t13m012@mail.ryukoku.ac.jp, 2 ishizaki@rins.ryukoku.ac.jp, 3 awai@ryutech.com

Abstract It is necessary to improve the characteristics of unloaded Q (Qu) and coupling coefficient (k) to improve the transmission property of the WPT system. Unloaded Q value is considered to be degraded due to the proximity effect between the coil wires and dielectric loss of the surrounding dielectric materials entering from the outside. We have tried various loop structures with the aim to improve the unloaded Q so far. Now we compare the characteristics of each resonator structure of three proposed types. And, we will investigate system characteristics to improve them further including the direct connection characteristics and tolerance to external influences.

Keyword 1-layered coil resonator, 2-layeded coil resonators, open spiral resonator, dielectric material, direct connection
