Research Interests


J.Choi Research Group Site

My primary research interests are in designing and implementing power conversion circuits. In power conversion systems, my research focuses on developing compact and efficient next-generation power electronics and extend this work to wireless power transfer for electric vehicles, biomedical devices and industrial applications. Also, I am interested in developing and utilizing wideband gap devices in high-power resonant converters operating at high frequencies.
