Key Technologies And New Developments Of Stationary-Dynamic Wireless Power Transfer-Video

Abstract: The wireless power transfer (WPT) technology is an attractive method that can deliver power through a large air gap without physical contact. Such technology has been successfully proved to be an excellent candidate to replace traditional methods. In recent years, WPT has drawn much attention due to its convenience, cleanness, and safety. This technology has been successfully applied to medical implants, mobile phones, electric vehicles, railway applications, etc. However, there are still some critical issues that should be addressed to achieve better performance. Key technologies and new developments of stationary/dynamic wireless power transfer, e.g., the realization of multi-output, current-stress optimization, and coil design for dynamic wireless power transfer (DWPT) will be introduced in this tutorial. Each technology will be introduced in detail and compared with the traditional method to show its feasibility. Finally, conclusions and future work will be concluded. This tutorial is suitable for someone with a basic knowledge of WPT and power electronics.
