Professor Li Yongdong was Invited a Talk on Large Capacity Power Electronic Techniques in the United States CURENT Research Center

During the 2016 IEEE ECCE(Energy Conversion Conference and Exposition)Conference, Professor Li Yongdong and Associate professor Zheng Zedong visited several engineering research centers sponsored by the National Natural Science Foundation of the United States, which were the FREEDM(Future Renewable Electrical Energy Delivery and Management)laboratory at the North Carolina State University, the CPES(Center for Power Electronics System) at the Virginia Tech University, and the CURENT(Center for Ultra-wide-area Resilient Electric Energy Transmission Networks)at the University of Tennessee. They also visited the WEMPEC laboratory at the University of Wisconsin – Madison.

On the afternoon of September 16th, 2016, at the United States, Prof. Li Yongdong was invited to give a report entitled "High-capacity multi-level DC-AC and AC-AC converters and their control" at the CURENT Research Center. He introduced the topology evolution principle and general PWM control method of large capacity multi - level DC - AC and AC - AC converters. All the participants discussed fiercely on this frontier scientific issue. The US CURENT Research Center is a National Science Foundation Engineering Research Center supported by the National Science Foundation and the US Department of Energy, and its headquarters locate at the University of Tennessee at Knoxville (UTK). Around 70 people attended this report, such as Prof. Kevin Tomsovic, Director of the CURENT Research Center, Prof. Yilu Liu, Associate Director of the US Academy of Engineering, Prof. Fred Wang, Deputy Director of the Center, and other related researchers and students.
