A Reconfigurable Coil Grid for Receiver Localization in Wireless Power Transfer and Magnetic Field Steering

The main purpose of Inductive Power Transmission (IPT) is efficient power transfer. Yet the ability to localize receiver itself an interesting goal. In Qi standards for wireless transfer, localization performed by using a coils array. resolution equal diameter in transmitter Decreasing transmitters increases but also reduces range IPT used inductive RFID (Radio Frequency Identification) where trade-off between and tag detection arises. This article proposes original system making it possible modify distance operation independently. Calculations simulations are implemented MATLAB software. Experiments low frequency validate method show capability with good accuracy, mean absolute error 4 mm localizing coil 1 cm radius positioned box dimensions 20*20*10 cm. Transmitter grid 9 3.3 radius. After localization, magnetic field steered direction obtain more
