Title: Current limiting FRT strategy of GFM converters
(Oral presentation)
Hi, I'm Gayoung!
I am a M.S. student in Electrical and Computer Engineering at Seoul National University advised by professor Shenghui Cui.
Currently, I am researching optimization of modulation and transformer design of dual-active bridge converters for high-efficiency EV DC fast charging.
I am grateful to be supported by Domestic Graduate Scholarships of SBS Foundation.
My research interests include data center power supplies, renewable integration and transportation electrification.
Outside of research, I love traveling around, taking photographs, and playing a guitar.
