摘要

This paper presents a compact inductive power transfer (IPT) system designed to power receivers enclosed within metallic structures, such as underground gas pipelines. The system eliminates perforation of the barrier and battery replacement, preserving structural integrity and enhancing safety and sustainability. A proposed circuit-based model, incorporating the metallic barrier as an auxiliary coil, inspired by eddy current testing methods, predicts a reduction in inductance and an increase in eddy current-induced resistance, guiding both coil design and manufacturing. Finite element analysis (FEA) and reduced order model (ROM)-based co-simulation in ANSYS software evaluate power transfer and refine coil design iteratively. A series-series topology prototype, without an additional DC-DC converter, achieves the highest reported efficiency of 23.7% at 2.89 W DC power transfer at 250 Hz, surpassing prior efficiencies of 2.5–15.5% through unmodified 1-mm-thick aluminum barrier. While with the lightest reported mass of 0.70 kg and miniature coils (26 × 25 mm), the proposed system offers unmatched efficiency and simplicity for powering low-power devices in constrained metallic environments such as gas pipelines.
