High Power Devices and Circuits Lab
Research Field
Professor Kung-Yen Lee received his Ph.D. and M.S. degrees in Electrical and Computer Engineering from Purdue University in the United States. He joined the faculty of the Department of Engineering Science and Ocean Engineering of National Taiwan University in 2010. He is the Director of the NTU-ITRI Nano Center of NTU since 2023. His current research interests have high power devices, power electronics, wide bandgap semiconductor materials, renewable energy.
The lab focuses on research in 4H-SiC power device design and reliability analysis. Given their superior characteristics, including high thermal conductivity, excellent breakdown voltage, and outstanding switching performance, 4H-SiC power devices play pivotal roles in high-power, high-temperature, and high-efficiency applications, such as electric vehicles, renewable energy systems, and advanced industrial power systems.
The recent research topics cover structural optimization and innovative design approaches for various power devices, particularly 4H-SiC power MOSFETs. In parallel, the lab conducts reliability evaluations—including short-circuit (SC) testing, unclamped inductive switching (UIS), and electrostatic discharge (ESD) testing to evaluate devices' robustness. Our research takes a deep dive into the physical mechanisms, degradation processes, and failure behaviors inside the device structures under extreme testing conditions.
