摘　　要：本文针对大功率三电平功率模块的低感母排进行了优化设计,提出了两种母排设计方案,首先根据杂散电感仿真分析低感母排的杂感参数及电流分布,然后通过双脉冲测试对比分析两种方案性能,最后得出,直流侧母排的两种设计差异较小,但PMN方案的杂散电感和电流分布更佳。Low inductance bus-bars for high power three-level power modules are optimized designed,and two bus-bars design schemes are proposed.Firstly,the stray inductance parameters of low inductance bus-bars and current distribution are analyzed according to the stray inductance simulation,and then the performances of the two schemes are compared and analyzed through the doublepulse test,and finally concludes that,the differences between the two designs of the DC side bus-bars are relatively small,but the stray inductance and current distribution of the PMN scheme are better.
