N2 - Inductive power transfer (IPT) systems for automated guided vehicles (AGVs) have emerged as a pivotal solution for industrial automation. Nevertheless, inherent mobility patterns of AGVs induce pronounced high-misalignment, causing dramatic coupling coefficient variations that critically degrade power transfer stability. This paper presents a reconfigurable IPT system with broad coupling immunity for highmisalignment AGVs charging. The proposed architecture implements intelligent inverter switching control to enable three operational modes in the primary compensation network, each generating a quasi-constant power plateau. Through synergistic parameter optimization, these plateaus are strategically concatenated to establish an ultra-wide effective coupling range. Experimental validation using a 500-W prototype demonstrates breakthrough performance: The system main-tains nearconstant power transmission (with less than 5% fluctuation) across a remarkable 400% coupling variation range (0.1-0.4), with measured efficiency sustaining 84.7-94.4%.
