**About the Editors**

**Ryszard Strzelecki** (M'97-SM'07) was born in Bydgoszcz, Poland. He received the M.Sc. and Ph.D. degrees in Electronic Engineering from the Department of Industrial Electronics, National Technical University of Ukraine "Kyiv Polytechnic Institute", Kyiv, Ukraine, in 1981 and 1984, respectively, and the Dr. Sc. degree in Electrical Engineering from the Institute of Electrodynamics, The National Academy of Sciences of Ukraine, Kyiv, in 1991. He is currently a full professor with the Gdansk University of Technology (Gda ´ nsk, Poland), co-head of the Laboratory of Power ´ Electronics and Automated Electric Drive, ITMO University (St. Petersburg, Russia), and Scientific Consultant for Power Electronics to the Management Board of AREX Ltd. In 2020, he was elected to the Committee on Electrical Engineering of the Polish Academy of Sciences. His research activity is concentrated on the topology, control, and industry application of power electronic conditioners, particularly for power quality enhancement and power flow control on distributed electrical networks.

**Galina Demidova** received her B.Sc., engineer, and Ph.D. degrees from ITMO University, Saint Petersburg, Russia. At present she is an Associate Professor at the Faculty of Control Systems and Robotics, Engineer of the Industrial Department of Precision Electromechanical Systems, and researcher of the International Scientific Laboratory "Power electronics and Automated Electric Drive ", at ITMO University. She has performed more than 20 R&D projects, dealing with control systems in digital electric power drives for tracking telescopes. She has authored or coauthored more than 50 conference and journal papers. She is co-Guest Editor in several Special Issues, and an organizer of the IEEE Conference. Her current research interests include adaptive control, fuzzy logic control, motion control, automatic control, fuzzy neural networks, hybrid intelligent systems, genetic algorithms, electromechanical systems, wind turbines, and multi-agent control

**Dmitri Vinnikov** Guest Editor 3: Prof. Dr. Dmitri Vinnikov Dmitri Vinnikov was born in Tallinn, Estonia, in 1976. He received the Dipl.Eng., M.Sc., and Dr.Sc.techn. degrees in Electrical Engineering from Tallinn University of Technology, Tallinn, Estonia, in 1999, 2001, and 2005, respectively. He is currently a Research Professor and the Head of the Power Electronics Group, Department of Electrical Power Engineering and Mechatronics, Tallinn University of Technology (Estonia), and a visiting professor in the Faculty of Control System and Robotics, ITMO University, Saint Petersburg, Russia. He is the Head of R&D and co-founder of Ubik Solutions LLC.— an Estonian start-up company dedicated to innovative & smart power electronics for renewable energy systems. Moreover, he is one of the founders and leading researchers of ZEBE—the Estonian Centre of Excellence, performing research toward the development of zero energy and resource efficient smart buildings and districts. He has authored or co-authored two books, five monographs, and one book chapter, as well as more than 300 published papers on power converter design and development, and is the holder of numerous patents and utility models in this field. His research interests include applied designs of power electronic converters and control systems, renewable energy conversion systems (photovoltaic and wind), impedance-source power converters, and implementation of wide bandgap power semiconductors. D. Vinnikov is a Chair of the IEEE Estonia Section .
