Abstract
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 high-misalignment 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%. © KIEE Electrical Machinery and Energy Conversion Systems.
