Seminar Title:
Challenges and Opportunities in High-Freq Wireless Power Transfer Systems
Abstract:
Modern electronic systems have rapidly transformed to realize automation, such as in factories or warehouses, and autonomous vehicles. As demand for automation grows, enabling technologies such as artificial intelligence, control, and intelligent charging systems become beneficial. However, while other technologies have been considerably revolutionized, the effort to develop an innovative and efficient charging system for automation has not. In this talk, I will first discuss high-frequency converters in wireless power transfer (WPT) systems to improve the efficiency and power density of the system. Then, I will introduce challenges and opportunities to design coupling coils for WPT systems at high frequencies. Finally, I will preview the direction of future work, such as developing efficient high-frequency converters for emerging applications.
About the speaker:
Jungwon Choi is an Assistant Professor in the Electrical and Computer Engineering department at the University of Washington. She received her Ph.D. degree in Electrical Engineering at Stanford University in 2019, M.S. in Electrical Engineering and Computer Science from the University of Michigan, Ann Arbor, in 2013, and B.S. in Electrical Engineering from Korea University in Seoul, Korea, in 2009. From 2019 to 2023, she was an assistant professor in the ECE department at the University of Minnesota, Twin Cities. Her research interests include high-frequency power converters, wireless power transfer for battery-powered vehicles, industrial and biomedical applications, magnetic designs, controls at high-frequencies, energy storage, and wide bandgap devices. In 2017, she was selected to the Rising Stars in EECS, received Unlock Idea awards from Lam Research in 2019 and 2020, and the National Science Foundation (NSF) CAREER award in 2021. In 2024, she was selected as a UPWAWRDS faculty.
