PROJECT TITLE :

Inner-Field Guiding Resonator for Efficient Wireless Power Transmission in Proximity Charging Condition

ABSTRACT:

An inner-field guiding resonator (IFGR) is presented for economical wireless power transmission (WPT) using resonant inductive coupling in proximity charging condition. The IFGR is inserted into a supply resonator to get an even magnetic field distribution which is the vital design factor of a proximity WPT system, as a result of it makes the system straightforward while not an adaptive matching technology. As the situation of the target resonator changes, the transmission efficiencies are simulated and measured to validate uniform- and high-transmission potency. To optimize the WPT system using the IFGR, the planning procedure is proposed. Considering the practical WPT system with ground plane, the proximity WPT system together with one or two mobile devices was designed and fabricated. The common of the entire potency in any respect positions on the source resonator was measured as 82.nine% (one mobile device) and eighty seven.1p.c (2 mobile devices), respectively. These results prove that an efficient proximity WPT system can be successfully designed using the IFGR.
