Straightforward Detection of Misalignment in a 3-Phase Wireless Power Transfer System

Dynamic Wireless Power Transfer (DWPT) systems offer a solution to both electric vehicle "range anxiety" and the need for expanded charging infrastructure, as vehicles could be wirelessly charged while driving on a roadway. However, alignment of the receiver significantly impacts the amount of power transfer that can be achieved. To address this challenge, researchers at Purdue University have developed a method for misalignment detection based on voltage and current on the receiver. Purdue's approach does not require any additional vehicle sensors hardware beyond what is needed for its role as a receiver. In addition, there is no need for communication between the vehicle system and the roadway. This technology has applications for in-road wireless charging systems for electric vehicles and automated driver assistance systems (ADAS).
