Abstract: Power semiconductor devices are the core of electrical energy conversion in power electronic equipment. As the world's largest consumer of power semiconductors, China faces a low self-sufficiency rate and a heavy reliance on imports, highlighting an urgent need for breakthroughs. Power semiconductor device simulation software, as an essential tool for multi-physics analysis and design optimization of devices, presents significant challenges in terms of high development complexity and low return on investment. Currently, almost all power semiconductor TCAD tools in use are developed by foreign companies such as Synopsys and Silvaco. Since 2019, the team has carried out the research and development work of power semiconductor device simulation tools. Based on the analysis of the physical models and solution difficulties of power semiconductor devices, this paper focuses on introducing the preliminary research progress of the two-dimensional simulation tool for power semiconductor devices, and conducts a detailed comparison with the calculation results of the world-leading commercial software Synopsys TCAD Sentaurus Device to verify the accuracy of the two-dimensional calculations.
