Guest Editorial Special Issue on Wireless Power Transfer

The papers in this special section focus on the technologies and applications that support wireless power transfer (WPT). The papers focus on state-of-the-art research, experimentation, and development, as well as future trends in the modeling, analysis, design, control, and testing of wireless power systems for mobile devices, electric vehicles (EV), etc. WPT is increasingly utilized in mobile devices, industrial applications, medical equipment, and transportation. Despite its advantages, however, WPT technology has not been adopted for widespread use. This delay may be because the technology remains quite expensive and less efficient than other available technologies. Furthermore, electromagnetic field and electromagnetic interference can become severe for a longer and higher power transfer, and they should be reasonably mitigated. Continued effort and innovation inWPT will be needed to open an era of wireless power adoption.
