中文摘要

宽禁带半导体的高开关速度易在封装内部激发谐振,导致电压过冲及电磁干扰。本文提出了一种改进的有限元分析(FEA)方法,用于精确提取功率模块的寄生参数,从而优化器件几何结构并降低寄生效应,提升高性能功率模块的设计可靠性。

English Abstract

The high edge rates of wide bandgap (WBG) semiconductors are known to excite resonances within device packaging, resulting in increased voltage overshoot and electromagnetic signatures. Simulation tools based on finite-element analysis (FEA) are commonly used during design to optimize device geometry and minimize parasitics. However, developing an accurate model to extract these parameters is chal...
