2023-10-04l Hit 193

The following article reported by a joint research team of Seoul National University (SNU) professor Jung-Ik Ha(corresponding author, Electric Power Research Institute), Myongji University professor Euihoon Chung(first author, submitted the article as a Ph.D. candidate in SNU), and MIT professor David Perreault, was chosen as the best paper in 2023 for the IEEE Journal of Emerging and Selected Topics in Industrial Electronics, a leading journal on industrial electronics. David Perreault, the co-author of this work, is one of the most acknowledged scientists in this field of research, whose graduate students are actively working as professors in UC Berkly, Standford, Princeton, Texas-Austin, and Cornell University.


Euihoon Chung, Jung-Ik Ha, Anas Al Bastami, and David J. Perreault, ”Impedance Compressing Matching Network Based on Two-Port Network Analysis for Wireless Power Transfer System,” IEEE Journal of Emerging and Selected Topics in Industrial Electronics, vol. 3, no. 3, pp. 432-442, July 2022.


The awarding ceremony will take place at IEEE Industrial Electronics Society’s most significant conference, the Annual Conference of the IEEE Industrial Electronics Society (IECON) in October 2023, where they will be given rewards and travel expenses.


In this research, the authors proposed a novel “impedance compressing network theory” that enables constant power transmission even when the position of the receptor varies (as in wireless transmission) and applied the theory to a wireless power transfer system. The impedance compressing/decompressing network theory can enhance tunability of the operating range of power semiconductors, leading to improvements in system response and efficiency of power converting systems, which can be utilized in RF power converters and high-frequency power converters.


Acknowledging significance of the invention and application of a new theory, this research was chosen as the best paper of the year by the journal’s judges.
