  • Abstract
    Presented is an adaptive method to improve the efficiency of wireless power transfer systems with axial-misalignment. With an impedance matching circuit, the system performance increases by 11.4% with 50% misalignment at a distance of 70 cm. The proposed system achieves 48.4% relative efficiency improvement compared to a system without the proposed technique for the axial-misalignment case.
