3.7 kW Wireless Power Transfer System for Electric Vehicle Charging
wireless power transfer · WPT · 6-DOF turntable · electric vehicle charging · coil offset characteristics · mutual inductance
Overview
This case studies a 3.7 kW wireless power transfer (WPT) system with focus on how different combinations of transmitting and receiving coil geometries affect offset performance. Output power, mutual inductance coefficient, and transfer efficiency are analyzed as functions of positional offset. Testing shows that circular-square coil combinations exhibit the best offset tolerance, providing a reference for high-efficiency wireless charging hardware design and experimental implementation. ---
