The research team of Dam Yun and Sunghyuk Choi from the Electric Energy Conversion Lab (Advisor: Professor Jung-Ik Ha) in the Department of Electrical and Computer Engineering at Seoul National University has received the Best Poster Award at the ‘IEEE/메이저 토토 사이트 2025 – 9th International Workshop on Power Supply on Chip’.

The research team presented a poster titled “Flying Capacitor Multi-Level Converter at Constant Resonant Frequency with Negative-Voltage-Blocking GaN Switch”, which focuses on low-voltage, high-current intermediate bus converter (IBC) technology for 48V power systems used in AI data centers. By applying a resonant flying capacitor multilevel (RFCML) converter that utilizes high-energy density capacitors, the team proposed a new approach that efficiently converts 48V to 12V while reducing peak inductor current, thereby achieving higher power density and efficiency compared to conventional methods

Held biennially, IEEE/메이저 토토 사이트 is the world’s leading international workshop in the field of integrated power conversion and power management technologies, serving as a forum where global experts from academia and industry gather to discuss the latest technological advancements.
