Power electronics across devices, converters, and electrical systems. My lab examines enhanced D-STATCOM design and analysis, dynamic AI workload modeling, and power peak shaving. These efforts address how power electronics can support rapidly changing electrical loads. SPECS Lab studies power converter design and analysis using wide-bandgap semiconductor devices, with research interests in WBG-based power electronics and high-frequency magnetics. Power dense motor drives for transportation, robotics, and drones. Research interests include converter modulation and control, electromagnetic interference, and reliability. Analytical models connect switching behavior, parasitic effects, and system performance. My research focuses on power conversion systems for the grid and AI data centers, WBG-based power electronics and high-frequency magnetics, and converter control, EMI, and reliability. Wide-bandgap power converters and high-frequency magnetics for efficient power conversion. Modulation, modeling, and control methods that address losses, interference, and device stress.
