Research on Optimization of Electromagnetic Compatibility for Electric Vehicles Wireless Power Transmission System

To enhance the electromagnetic compatibility (EMC) performance of electric vehicles (EVs) wireless power transmission (WPT) systems, this paper establishes an equivalent simulation model and analyzes its fundamental electromagnetic characteristics. Addressing the issue of significant leakage magnetic field intensity in certain areas, an optimized design scheme for the WPT system is proposed. The superiority of this optimized scheme is then validated through simulation analysis. The comparative results demonstrate that, without compromising the system’s transmission efficiency, the proposed optimization significantly reduces the leakage magnetic field distribution around the WPT system. This not only improves the overall EMC performance but also ensures greater electromagnetic safety for special drivers or passengers wearing cardiac pacemakers.
