This paper presents an advanced Wireless Power Transfer (WPT) system for electric vehicles (EVs) featuring Active Load Impedance Matching (ALIM) at the rectification stage. Unlike traditional synchronous rectification, ALIM dynamically adjusts load impedance, optimizing energy transfer efficiency and reducing thermal stresses, costs, mass. The incorporates two circuits optimized distinct frequency bands: one operates below 10 kHz using standard copper wiring cost-effectiveness, other 85 kHz, which significantly reduces mass of onboard coil magnetic circuit while ensuring interoperability according to SAE J2954 standard. Our approach enhances charging across various operating conditions, improves management, minimizes maintenance costs. Additionally, it enables partial compensation vehicle misalignment ground assembly further boosting interoperability. Experimental results demonstrate a notable increase in reduction mass, confirming superiority ALIM-equipped WPT over conventional solutions. underscores potential advance scalability, efficiency, economic viability wireless EV technology, promoting broader adoption sustainability infrastructures. By providing comprehensive solution that addresses key challenges charging, our work paves way more efficient cost-effective systems.
