Title: High Frequency and Very High Frequency Power Conversion and Transmission
Abstract: Increasing the switching frequency is the trend for power electronics with the fast development and innovation of the Internet of Things, artificial intelligence and datacenter, 5G, space exploration, robotics and drones, healthcare, and semiconductor manufacturing. High frequency (HF, 3-30 MHz) and very high frequency (VHF, 30-300 MHz) power electronics stand out for various reasons besides the well-known advantages of miniaturization and integration. At higher frequencies, radiative electromagnetic waves contribute; distributed energy storage and transmission lines get involved together with lumped circuit elements. Currently, VHF power is a blue ocean with potential fortune and treasure, waiting for navigators and divers to explore and discover them.
In this seminar, I will first present the motivations to go to higher frequencies for power conversion and transmission. Next, I will focus on VHF wireless power transfer to illustrate the design challenges and solutions, including VHF gate drivers, electromagnetics, power amplifiers, and power architectures. Charging scenarios will be investigated for different applications in wireless powering the Internet of Things. Lastly, I will highlight potential fundamental research questions and applications of HF and VHF power conversion and transmission for the future.
Bio: Xin Zan received his B.E. degree in electrical engineering and automation and the Excellent Graduate Award from Tsinghua University, Beijing, China, in 2016. He is currently working towards his Ph.D. degree in the Department of Electrical Engineering and Computer Science at the University of Michigan, Ann Arbor with an anticipated graduation date in April 2022. His research focuses on high frequency and very high frequency power electronics and pulse power electronics.
Mr. Zan was the recipient of the IEEE PELS ECCE Best Student Project Demonstration on Emerging Technology 2nd Prize Award in 2018, the IEEE PELS Best ECCE Paper on Emerging Technology Award Oral Presentation in 2019, the Richard F. and Eleanor A. Towner Prize for Distinguished Academic Achievement from the University of Michigan in 2019, the Rackham Predoctoral Fellowship from the University of Michigan in 2021, and the Rackham Graduate Student Research Grant from the University of Michigan in 2021.
