Abstract

This paper presents an approach to detect the lateral coil misalignment for the dynamic wireless charging system using a tunneling magnetoresistive (TMR) sensor array. The component of the magnetic field generated from the transmitting coil can directly provide the information of the coil misalignment between transmitting and receiving coils. A sensor array composed of 15 uniaxial TMR sensors was implemented to measure the vector magnetic field for detecting the coil misalignment. Both 3-D finite-element method modeling and experimental results over a relatively large misalignment range were presented to substantiate the effectiveness and feasibility of the proposed approach.
