摘要
针对80kVA/400A变流器H桥母线排的设计要求,使用ANSOFT MAXWELL有限元分析软件比较了不同设计原则下杂散电感参数的变化,并提出了一种新型的优化母线排结构,较少了IGBT模块的关断过冲电压,并优化了高频电流的分布。通过仿真和实验分别证实了新型母线排的良好测试结果,最后给出了系统结构和实验波形。
For the design requirements of 80kVA/400A H-bridge converter busbars,this paper compared the changes of the stray inductance under different design parameters using the finite element analysis software ANSOFT MAXWELL,and proposes a new optimistic configuration of busbar structure,it can reduce the voltage overshoots of the IGBT,optimize the high-frequency current distribution.the new type of busbar was Confirmed by simulation and experiment to be a good test results.Finally provided the system structure and experimental waveforms.
