Electromagnetic Compatibility for Wireless Power Transfer

Abstract — Electromagnetic Compatibility for Wireless Power Transfer
Wireless power transfer (WPT) is one of the most promising technologies in recent years, which is expected to provide ultimate convenience and safety of electronic systems and to create huge market in mobile devices, electric vehicles, biomedical implants, and IoT sensor network applications in the near future. However, as the power of the WPT system increases and the distance from Tx to Rx increases, the interference to other electronic system and the electromagnetic field effect on the human body becomes a serious problem. The electromagnetic compatibility (EMC) issues of WPT systems are very critical in the commercialization of the wireless power devices.  In this lecture, the EMC aspects of magnetic resonant and microwave WPT systems are discussed in terms of electromagnetic field generation and solutions in different applications. Although the research on the various EMC solutions for general electronic systems has been done for decades, most of EMC techniques for the reduction of unwanted electromagnetic fields are not applicable due to physical limitation of the WPT system. Instead, recent advances in electromagnetic field reduction methods for WPT systems such as magnetic field shaping, active/passive/reactive shielding, field cancelling, and harmonic filtering techniques for a magnetic resonant WPT system are investigated.  In addition, retro-directive and time reversal techniques for microwave power transmission are developed, as well as traditional electromagnetic interference reduction methods. This lecture also covers the trend of standardization of WPT technology as the EMC problem of the WPT system is the key issue in industry. The future direction of EMC standard issues of a WPT system such as on frequency allocation, field regulation, and standard measurement of electromagnetic field from a WPT system is explained.

Biography:

Seungyoung Ahn received the B.S., M.S., and Ph.D. degrees in electrical engineering from the Korea Advanced Institute of Science and Technology (KAIST), Daejeon, Korea, in 1998, 2000, and 2005, respectively. He is currently an Assistant Professor with the Cho Chun Shik Graduate School for Green Transportation, KAIST. His research interests include wireless power transfer (WPT) system design and electromagnetic compatibility (EMC) design for electric vehicle and digital systems, High-Frequency Modeling of Through-Silicon Via for High Density Package and Biomedical Device using Wireless Power Transfer Technology. He has published over 70 journal and 100 international conference papers, and has been granted over 10 patents. He has given extensive invited talks on Wireless Power Transfer. Following is summary of his presentation options.
