N2 - In this paper, a quantitative analysis of the cross-coupling effect for multi-objective wireless power transfer (WPT) is presented and a relevant method to eliminate the influence is implemented. Based on the exemplified two-pickup and three-pickup WPT systems, the wirelessly transmitted power and efficiency are significantly affected by the cross-coupling effects among pickup coils. Meanwhile, the zero-phase angle (ZPA) operation of the primary side is deteriorated due to the existence of the cross-coupling effect. Accordingly, a cross-coupling cancellation method is proposed to regulate the primary exciting current back to its original value and recover the primary side back to the ZPA operation. Both the simulated and experimental results are provided to verify the feasibility of the proposed cancelation method.
