Won-Hyo Jung, a Ph.D. candidate in the Electrical Energy Conversion Laboratory (led by Advising Professor Jung-Ik Ha) within the Department of Electrical and Computer Engineering, received the "Outstanding Paper Award for Young Engineers" at the 2026 International Power Electronics Conference (IPEC-Nagasaki 2026 -ECCE ASIA-), held in Nagasaki, Japan, from May 31st to June 4th.

The award-winning paper is titled “Charge Pump Circuits for Negative Voltage Turn-Off in Gate Drivers.” This research presents a novel method for generating the negative voltage required to drive switches in high-voltage, high-current circuits using SiC (Silicon Carbide) switches, completely eliminating the need for isolated DC-DC converters.

Held annually, ECCE ASIA is the largest international conference in the power electronics field within Asia, serving as a premier platform for sharing next-generation energy conversion technologies and the latest research achievements.
