Dodatkowe informacje

In 1997, he graduated from the Electronic Technical School in Kielce, obtaining the professional title of electronics technician with a specialization in electrical and electronic industrial automation. He obtained the MSc degree in the field of Automation and Robotics in 2003 at the Faculty of Electrical Engineering of the Warsaw University of Technology. He received his PhD degree and postdoctoral degree (habilitation) in the discipline of Electrical Engineering from the Faculty of Electrical Engineering of the Warsaw University of Technology in 2005 and 2019, respectively. He was awarded the academic title of professor in 2024.

From 2006 to 2008, he worked as a researcher in the European project HOPE, coordinated by Siemens Corporate Technology under the 6th EU Framework Programme. Between 2008 and 2010, he was a key researcher in the European project CRISTAL, coordinated by Anglia Ruskin University (Cambridge, UK). Since 2009, he has held the position of assistant professor. He completed a two-month research internship at Mondragon University (Spain) in 2009 and a one-year research internship at Universitat Politècnica de Catalunya (Spain) in 2012 as part of a scholarship from the Polish Minister of Science and Higher Education. Since 2019, he has been employed as an associate professor, and since 2024, he has held the position of full professor at the Department of Electric Drives at the Faculty of Electrical Engineering of the Warsaw University of Technology. He served as Deputy Chair of the Scientific Council for the Discipline of Automatic Control, Electronics, Electrical Engineering, and Space Technologies for the 2020-2024 and 2025-2028 terms and is a member of the Scientific Council of the University Research Center for Aeronautics and Space.

He is the author or co-author of over one hundred publications in international and national scientific journals and conferences, including forty articles in journals listed in the Journal Citation Reports. Additionally, he is a co-author of the scientific monograph "Doubly Fed Induction Machine, Modeling and Control for Wind Energy Generation," published by John Wiley as part of the IEEE Press Series on Power Engineering in 2011 and reprinted in Chinese by China Machine Press in 2015. He has also contributed three book chapters published by John Wiley, Springer, and CRC Press. He has delivered two plenary speeches at the EVER conference (Monte Carlo, Monaco) in 2015 and the OPTIM-ACEMP conference (Brașov, Romania) in 2017. He has received eight awards from the Rector of the Warsaw University of Technology for scientific achievements, including one individual award, three distinctions for publications at international scientific conferences, and a medal from the Łódź branch of Polish Society for Theoretical and Applied Electrical Engineering for "outstanding achievement in the field of theoretical electrical engineering with high application potential," presented in an article at the national SENE’19 conference. He has supervised two defended doctoral dissertations, served as an auxiliary supervisor for three defended dissertations (one with distinction), and mentored two foreign postdoctoral research fellows.

Throughout his scientific career, he has carried out numerous research projects. He was the principal investigator of a research project funded by the Ministry of Science and Higher Education from 2008 to 2011, two OPUS projects funded by the National Science Centre from 2012 to 2014 and 2017 to 2020, and a team leader in a research project funded by the National Centre for Research and Development under the Applied Research Programme from 2015 to 2019. He was also a team leader in a project funded by the National Centre for Research and Development under the "Fast Track" programme from 2021 to 2023 and a key researcher in five other scientific research projects.

His scientific achievements, resulting from conducted research, are primarily related to the field of electrical energy generation and conversion using power electronic systems. Many of his research papers focus on a comprehensive approach to controlling the doubly-fed induction machine, widely used in wind turbines with megawatt-scale power output. His most significant work in this field involves:

island operation of the generator under asymmetric and nonlinear load conditions, with compensation for asymmetries and voltage harmonics,
grid-connected operation of the generator under voltage asymmetry and harmonics, compensating for oscillations in electromagnetic torque caused by the negative sequence component of the machine flux,
operation of the generator as a DC power source equipped with a diode rectifier connected to the stator, with reduced electromagnetic torque ripple and DC voltage oscillations.

His research in this area has been published in leading international journals (IEEE Transactions on Industrial Electronics, IEEE Transactions on Power Electronics, IEEE Transactions on Sustainable Energy, IEEE Transactions on Energy Conversion, Electric Power Systems Research).

Another significant achievement concerns the control of a three-phase power electronic converter under voltage asymmetry and harmonics. His research includes control objectives for grid-connected converters beyond merely achieving a sinusoidal and symmetrical current waveform. The intentional introduction of asymmetry in converter current enables partial compensation of voltage imbalances at the grid connection point. His studies have extended the concept of treating the power grid as a virtual electric machine and proposed a control strategy based on virtual torque. Particularly noteworthy are the recently developed methods that use non-Cartesian coordinate systems, where control variables remain constant over time despite asymmetry and harmonics in phase currents and grid voltage. His work in this field has also been published in top-tier journals (IEEE Transactions on Industrial Electronics, IEEE Transactions on Power Electronics, IEEE Transactions on Industry Applications, IEEE Journal on Emerging and Selected Topics in Power Electronics, IEEE Transactions on Power Delivery).

A major achievement of his research team was the development of an electric propulsion system for a hydrogen fuel cell-powered motor glider. The research focused on designing an IGBT-based inverter system for the electric motor and an interleaved DC/DC boost converter using SiC technology for the fuel cell, ensuring safe and uninterrupted operation in case of communication loss between devices and the onboard master computer. Conducted in collaboration with teams from the Faculty of Power and Aeronautical Engineering at the Warsaw University of Technology, as well as AGH University of Science and Technology and Rzeszów University of Technology, the research led to the development of Poland's first lightweight aircraft platform powered by hydrogen fuel cells.

Since 2021, he has been serving as an associate editor for the journal Power Electronics and Drives. He is a member of the program committees for the international conferences Electric Vehicles and Renewable Energies (EVER) and Sustainable Mobility Applications, Renewables, and Technology (SMART), as well as the national conference Control in Power Electronics and Electric Drives (SENE). He has been a member of IEEE since 2010 (Senior Member since 2018).
