摘要: 柔性直流输电技术的不断发展对应用在柔性直流输电系统中的绝缘栅双极晶体管(IGBT)器件提出了更多的要求。压接型IGBT器件因符合柔性直流输电系统等领域高电压、大电流以及高功率密度的发展需求而得到重视,易于串联的特性使其非常适用于高压应用领域。目前以WESTCODE、TOSHIBA公司为代表的凸台式封装结构和以ABB公司为代表的弹簧式封装结构的2种压接型IGBT器件已成功应用到柔性直流输电工程中。基于有限元法建立了2种压接型IGBT器件的仿真模型,分别针对器件2种不同工况(正常加压未工作和正常工作状态)对比分析了其内部的压力分布。仿真结果表明,2种结构的压接型IGBT器件在正常加压状态下压力分布均比较均匀,由于弹簧结构的存在使得弹簧式压接型IGBT器件在正常工作状态下压力分布更为均匀。最后基于仿真分析,对压接型IGBT器件的结构优化提出了可能的解决方案。

Abstract: The continuous development of flexible High Voltage Direct Current (HVDC) transmission system poses more requirements to the insulated gate bipolar transistor (IGBT) devices. Press Pack IGBTs (PPI) are valued for their development demand of high voltage, high current and high power in the areas of flexible HVDC transmission system. At present, two types of Press Pack IGBTs with pedestal structure represented by WESTCODE and TOSHIBA as well as Stakpak structure represented by ABB, have been successfully applied in the flexible HVDC transmission projects. These two kinds of structural models of the Press Pack IGBTs based on finite element method are established. The pressure distributions within these two kinds of Press-Pack IGBTs in normal pressurization conditions and normal working conditions are analyzed. The simulation results show that the pressure distributions within both types of Press-Pack IGBTs in normal pressurization conditions are relatively uniform, while the pressure distribution of the stakpak structure is more uniform in normal working conditions. Finally, based on the simulation results, this paper proposes possible solutions to the structural optimization of the Press Pack IGBTs.

Key words: flexible HVDC transmission system, press pack IGBTs, pedestal PPI, stakpak PPI, clamping force distribution
