Curvature Angle Splitting Suppression and Optimization on Nonplanar Coils Used in Wireless Charging System

This article investigates the tapered and curved coil used in wireless power transfer (WPT) system for the purpose of improving flexibility in specific applications. The WPT transmission performance is always declined by coil bending. To solve this problem, the models of the coils are built, and their magnetic flux are analyzed. The phenomenon of curvature angle splitting is studied, the mechanism is revealed, and the method is proposed to avoid...
