Wireless Power Transfer Coil Array

On wireless power transfer wpt based on resonant coupling.

Wireless power transfer coil array. Wireless power transfer sheet cuttable electronics thin lm coil array acm reference format. The use of metamaterials and array of coupled resonators. Additional key w ords and phrases. Two major technologies will be discussed.

With a slab of metamaterial the near field coupling between two resonant coils can be enhanced. In comparison to the conventional single tx coil iwpt the overall power gain can be improved by 17 3 db at a typical power transfer range of 2 5 mm while a 1 mm misalignment only. Two major technologies will be discussed. Progress on wireless power transfer wpt based on resonant coupling.

Other new additions include a high power coil we wpcc 760308101311 with 400 w output and a flat version two coils whose respective heights of 2 8 mm and 3 1 mm are only half as high as those of wireless power transfer coils combine charging function and nfc.

With a slab of metamaterial the near field coupling between two resonant coils can be enhanced. Wireless power transfer coils we wpcc. At varying power transfer ranges the power transfer gain and misalignment tolerance are measured for both the single coil and line array systems respectively. In this article we introduce a novel array based system for inductive wireless power transfer wpt applications and a procedure for its design which can be interpreted as a generalization of the traditional three coil systems where the intermediate passive resonant coil i e the transmitter is replaced with an array of nonresonant concentric loops.
