Ph.D. candidate Dam Yun (1st Author) from the Electric Energy Conversion Lab (Advisor: Professor Jung-Ik Ha) in the Department of Electrical and Computer Engineering at Seoul National University has won the 2025 Second Place Prize Paper Award from the international academic journal, IEEE Journal of Emerging and Selected Topics in Power Electronics (JESTPE).

​The award-winning paper is titled, "Flying Capacitor Multilevel Converter at Constant Resonant Frequency with Negative-Voltage-Blocking GaN Switch."

​This research focuses on low-voltage, high-current Intermediate Bus Converter (IBC) technology applied to 48V power systems in AI data centers. By utilizing a Resonant Flying Capacitor Multilevel (RFCML) structure, the converter steps down 48V to 12V. The study proposes a method to achieve higher power density and efficiency compared to conventional methods by lowering the peak inductor current.

​IEEE JESTPE is a prestigious academic journal in the field of power electronics, jointly published by the IEEE Industry Applications Society (IAS) and the IEEE Power Electronics Society (PELS).
