Design and optimization of high-efficiency anti-misalignment resonant coils for wireless charging of electric vehicles

This study introduces a new way to improve the anti-misalignment capability of wireless power transfer (WPT) systems for electric vehicles (EVs) by design and optimisation of the resonant coils. Addressing the common challenge of coil alignment, which has a significant impact on WPT. A new resona...
