A review of high-power wireless power transfer

High-power wireless power transfer (HPWPT) is a key enabling technology for the adoption of battery electric vehicles (BEVs). As the technology has matured from year to year, discussions of standardization and many commercial partners have come to the area. Much research has been done in this area, and the realization of high-power charging has been furthered by the introduction of new techniques and devices. Here, current high-power WPT systems are reviewed and the passive elements, devices, subsystems, and techniques that have been developed to reach high-power levels are briefly detailed.
