Abstract

This research examines the impact of magnetic materials on wireless power transfer (WPT) systems for electric vehicles (EVs), focusing on 3D coil and coupler design using Ansys Maxwell. It explores how material choice influences WPT performance and reliability, analyzing parameters like coupling (k), mutual (M), and self-inductance (L) alongside magnetic flux density (B), field strength (H), energy, and thermal effects across air gaps (40-200 mm). Matlab verifies output voltage, current, power, and power transfer efficiency (PTE). Results show that ferrite achieves a peak PTE of 94.3% at an 80 mm gap, with a 30.4 kg weight and 400 × 400 × 20 mm dimensions, while alloy steel yields 73.9% PTE at 50.67 kg. The study aids in selecting materials to optimize PTE, reduce losses, ensure safety, and improve reliability, advancing WPT technology for efficient EV charging infrastructure.
