Power electronics represents one of the fundamental pillars of modern power industry and electromobility. It is an exceptionally complex field, referred to by researchers at the Faculty of Electrical Engineering, CTU as the “decathlon of electrical engineering,” as it integrates knowledge from materials science, control systems, power components, and system-level management. This comprehensive approach is also reflected in the power electronics research conducted at the faculty.
The aim of the seminar is to provide an overview of currently researched topics in this field. The morning session will consist of expert lectures, with a strong emphasis on discussion regarding the transfer of scientific results into industrial practice. In the afternoon, participants may choose one of two workshops. The event will conclude with a guided tour of the laboratories of the Department of Electric Drives and Traction.
Workshops: Battery Diagnostics and Power Electronics Simulation
The first workshop will focus on diagnostics of lithium-ion batteries, which remain one of the most expensive components in electric vehicle manufacturing. This is partly due to the difficulty and time-consuming nature of diagnosing the current state of battery degradation and predicting its remaining lifespan. As a result, batteries are often replaced preventively earlier than necessary. Participants will gain hands-on experience with various testing methods for battery diagnostics and learn how to evaluate measured data and extract information about the state of degradation.
The workshop will be led by Kateřina Nováková, who developed a diagnostic method during her doctoral studies at the Faculty of Electrical Engineering, CTU that allows for a more accurate estimation of the actual condition of electric vehicle batteries and can extend their lifespan by up to 10 percent. She is currently collaborating with Kolibrik.net on implementing this solution in practice.
The second afternoon workshop will focus on real-time simulation of power electronics (HIL). It will be led by Filip Baum, whose doctoral research at the Department of Electric Drives and Traction focuses on modulation strategies for power converters used in electric drives. He regularly publishes his research in top scientific journals and has received the Vice-Dean's Award for PhD-authored Papers in Top Journals twice. He is also a member of the Advanced Electric Drives and Power Electronics (AEDPE) group, led by Ondřej Lipčák.
