| Popis: | Sis, Seyit Ahmet (Balikesir Author) Flux pipe couplers are compact coils used in wireless power transfer (WPT) applications. The first part of this paper investigates the effect number of sub-coils on the magnetic characteristics. Flux pipe couplers with more than two sub-coils exhibit higher coupling coefficient as compared to traditional flux pipe couplers with two sub-coils. Furthermore, multi sub-coil flux pipe couplers better distribute the magnetic flux inside the core, making them attractive in high power applications. The second part presents an experimental WPT system employing multi sub-coil flux pipe couplers with three sub-coils. More than 82% power transfer efficiency is observed when couplers are separated with 100 mm vertical gap. Lateral misalignments up to 200 mm are then applied, and meantime, the separation between sub-coils is varied for achieving maximum efficiency. A near-constant efficiency is obtained up to 150 mm misalignment. Therefore, this paper announces another potential use of flux pipe couplers realizing an adaptive WPT system. |
