Wide Bandgap Power Semiconductor Devices and Future Electric Power Delivery System

Published on


The focus of the talk will be on a R&D journey from microelectronics to power electronics to smart grid energy system, or from microsystem to complex large scale system, and the importance of multidisciplinary team oriented research. Dr. Huang proposed the FREEDM (Future Renewable Electric Energy Delivery and Management) System in 2007 as a novel architecture suitable for plug-and-play of distributed renewable energy and distributed energy storage devices. Motivated by the success of the Information Internet, the architecture was put forward as a transformative platform for an Energy Internet. In the Information Internet, people share information in a plug and play manner. In the envisioned ‘Energy Internet’, a vision for sharing of the energy is proposed for ordinary citizen and home owners. Key enabling technologies required to achieve such a vision will be discussed. Among many of the key technologies, the development of advanced wide bandgap power semiconductor devices and medium voltage power electronics systems will be discussed and highlighted.



Dr. Alex Huang received his B.Sc. degree from Zhejiang University, China in 1983 and his M.Sc. degree from Chengdu Institute of Radio Engineering, China in 1986, both in electrical engineering. He received his Ph.D. from Cambridge University, UK in 1992. From 1994 to 2004, he was a professor at Center for Power Electronics System (an NSF ERC) at Virginia Tech. Since 2004, he has been a professor of electrical engineering at North Carolina State University and he is now the Progress Energy Distinguished Professor of Electrical and Computer Engineering. He is the founding director of NCSU’s Advanced Transportation Energy Center (ATEC). In 2008, he led a consortium of five US universities and established the NSF FREEDM Systems ERC. Today, FREEDM Systems ERC is one of the most successful ERCs with support from more than 52 companies. Dr. Huang is also the lead PI and visionary leader behind NCSU’s recent success in establishing the next generation power electronics manufacturing innovation institute.

Dr. Huang’s research areas are power semiconductor devices, power management integrated circuits, power electronics and its emerging applications, and electric power delivery and management system. He has published more than 380 papers in journals and conference proceedings, and is the inventor of more than 20 US patents. He has mentored and graduated more than 60 Ph.D. and master students. Dr. Huang is a fellow of IEEE and Zhejiang University Qiushi Chair Professor, and the recipient of the prestigious R&D 100 and MIT Technology Magazine awards.
