Overview

This research demonstrates improved shielding in wireless power transfer systems for electric vehicles, suggesting enhanced efficiency.

Key Points

  • An active-shielded single-sided magnetic core structure effectively minimizes leakage magnetic fields, achieving below 27 μT.
  • Transmission efficiency exceeds 88% under both aligned and offset conditions, showcasing substantial energy transfer capability.
  • A mathematical model and optimization method were developed to reduce shielding material volume without compromising safety.
  • Simulation and experimental validation confirm the effectiveness of the proposed structure in electric vehicle applications.
