Mahmoud A. Sayed was born in Qena Prefecture, Egypt, in 1974. He received the B.Sc. and M.Sc. degrees in electrical engineering from Minia University, Minya, Egypt, in 1997 and 2001, respectively, and the Ph.D. degree in electrical engineering from Nagoya Institute of Technology, Nagoya, Japan, in 2010. Since 1999, he has been with the Department of Electrical Engineering, Faculty of Energy Engineering, Aswan University, Aswan, Egypt, first as an Administrator and since 2001 as a Lecturer. Since 2010, he has been with the Faculty of Engineering, South Valley University, Qena, Egypt, first as an Assistant Professor and since 2015 as an Associate Professor. He is currently working with the Department of Electrical and Mechanical Engineering at Nagoya Institute of Technology. His research interests include voltage regulation and loss minimization of electrical distribution systems using series and shunt pulse-width modulation (PWM) converters, PWM techniques for bidirectional ac/dc and direct ac/ac converters, in addition to renewable energy applications and machine drives. Dr. Sayed is a Senior Member of the IEEE Power Electronics and Industry Application Societies.
