Xinbo Ruan was born in Hubei Province, China, in 1970. He received his BS and PhD in Electrical Engineering from Nanjing University of Aeronautics and Astronautics (NUAA), China, in 1991 and 1996, respectively. In 1996, he joined the Faculty of Electrical Engineering Teaching and Research Division, NUAA, where he became a Professor at the College of Automation Engineering in 2002 and engaged in teaching and research in the field of power electronics. From August to October 2007, he was a Research Fellow at the Department of Electronic and Information Engineering, Hong Kong Polytechnic University, Hong Kong, China. From March 2008 to September 2011, he was also with the School of Electrical and Electronic Engineering, Huazhong University of Science and Technology, China. He is also a Guest Professor at Beijing Jiaotong University, China; Hefei University of Technology, China; and Wuhan University, China. He has authored or co-authored nine books and more than 300 technical papers published in journals and conference proceedings. His main research interests include soft-switching DC-DC converters, soft-switching inverters, power-factor correction converters, modeling of converters, power electronics system integration, and renewable energy generation systems. Dr. Ruan received the Delta Scholarship from the Delta Environment and Education Fund in 2003 and became the Special Appointed Professor of the Ministry of Education Chang Jiang Scholar Program in 2007. From 2005 to 2013, and again from 2017, he served as Vice President of the China Power Supply Society, and since 2008 he has been a member of the Technical Committee on Renewable Energy Systems within the IEEE Industrial Electronics Society. Currently, he serves as an Associate Editor for IEEE Transactions on Industrial Electronics,  IEEE Transactions on Power Electronics, IEEE Journal of Emerging and Selected Topics on Power Electronics and IEEE Transactions on Circuits and Systems-II.
