Semiconductor power devices are the fundamental building blocks of modern power electronics, enabling the efficient conversion and control of electrical energy in everything from electric vehicles (EVs) to renewable energy grids. As systems demand higher power densities and faster switching, understanding the interplay between their intrinsic physics, operational characteristics, and long-term reliability is essential for engineers and researchers. 1.
