My research interests focus on power electronics based on electrical engineering, with emphasis on high-power and high-frequency energy conversion and control technologies. A primary area of my research is power electronic systems for atmospheric-pressure plasma generation. Atmospheric-pressure plasma can operate without vacuum equipment and is applicable to surface treatment, sterilization, and defense-related applications. Stable plasma generation requires advanced high-frequency and high-voltage power conversion techniques. My work has focused on resonant converter topologies, high-frequency switching control, and power supply design considering the nonlinear characteristics of plasma loads. I also have research interests in power electronics for induction heating systems. Induction heating enables rapid and efficient non-contact heating and is widely used in defense manufacturing and metal processing. My research emphasizes high-efficiency inverter design, resonant frequency control, and stable operation under varying load conditions. In addition, I am interested in marine technology applications, particularly power electronics for sonar systems. Sonar systems require reliable and low-noise power supplies for stable underwater operation. My research explores high-reliability power conversion and robust power system design for marine defense applications.
