In WPT-MRC (Wireless Power Transfer via Magnetic Resonance Coupling) systems, the resonator coils need to be aligned for maximum efficiency, and any misalignment between resonator coils can result in a significant drop in output efficiency. Therefore, improving the anti-misalignment capability of WPT systems is an important consideration for practical applications. The paper has proposed a NUDCT (Non-Uniformly Distributed Coil Turns) coupler with uneven turns that generates a uniform magnetic field to improve anti-misalignment capability of WPT-MRC systems. The proposed NUDCT resonator has been optimized using GA (Genetic Algorithm), and the theoretical analysis of the magnetic field in case of misalignment has been presented. The paper has also validated the WPT-MRC system’s transmission performance using the optimized coil. The results indicate that the magnetic field generated by NUDCT provides better uniformity under misalignment and higher system efficiency.
