This paper, based on the partial element equivalent circuit ( PEEC), analysis the power converter of bus bar row, extract the parasitic inductance and parasitic resistance, and then bus bar structure is optimized. 本文基于部分元等效电路理论(partialelementequivalentcircuit,PEEC)对功率变换器母线排进行了分析,提取其寄生电感和寄生电阻,并对母线排的结构进行了优化设计。
