摘　　要：针对阻感负载模型不能精确反映出吸收电容等缓冲器件对复合母排特性影响的问题,提出了复合母排多端口参数矩阵的建模方法。利用该复合母排多端口电路仿真模型,对并联器件的电流不均度以及吸收电容容值对功率器件过电压性能的影响进行了分析,仿真结果可指导复合母排优化设计及吸收电容的选型。通过对逆变器系统的仿真和试验,对比了中点电流的频谱,验证了复合母排多端口电路仿真模型的有效性。To solve the problem of inaccurate description of effects by such buffers as snubber capacitor and clike on the daracteristics of compound bus-bur,firstly a method for parameter matrix of multiport circuit modeling is proposed.And then,by utilizing the multiport circuit simulation models of the compound bus-bars,the current inequality between parallel devices,the influence on the over-voltage of snubber capacitors are all analyzed by simulations.The simulation results can be used to guide the designs of the compound bus-bars and snubber capacitors.Finally,the contrast of the spectrum of the midpoint current between simulation results and experimental data validates the multiport circuit simulation models of the compound bus-bars.
