  Introduction Power electronic devices, also known as power semiconductor devices, are electronic components used in circuits for power conversion and control, specifically for high-power applications (typically referring to current in the range of tens to thousands of amperes and voltages of several hundred volts or higher). Power devices are capable of handling and controlling large currents and voltages, and they offer advantages such as high efficiency, high reliability, and high-speed operation. They play a critical role in various application scenarios. The main types of power semiconductor devices include diodes, thyristors, and transistors. Among them, diodes and thyristors have relatively mature and simple manufacturing processes, while transistors, particularly insulated-gate bipolar transistors (IGBTs), metal-oxide-semiconductor field-effect transistors (MOSFETs), and bipolar junction transistors (BJTs), have the largest market share.   MOSFETs and IGBTs are import...
