摘要 作为城市轨道交通车辆的关键子系统的牵引变流器,其可靠性受到了广泛的关注。根据工业调查,绝缘栅双极性晶体管(IGBT)是电力电子变换器中最易受损的部件之一。IGBT模块的工作状态取决于牵引电机的输出功率。牵引变流器运行工况的变化会导致IGBT结温的波动,从而对IGBT造成损伤。因此,为了节省成本和提高系统可靠性,该文对IGBT可靠性技术进行了研究。首先,进行基于任务剖面的城市轨道交通牵引变流器IGBT模块的寿命预测。然后,分析牵引变流器控制方式对IGBT寿命的影响;最后,研究以可靠性为导向的牵引变流器控制策略,该策略能够提高牵引变流器的可靠性和可用性。

Abstract:Traction converters are the key subsystem of urban rail transit trains, whose reliability has received extensive attention. According to an industry-based survey, IGBTs are the most fragile components in power electronic converters. The working condition of IGBT modules is subject to the output power of traction motors. The changes in the operations of the traction inverters could cause fluctuations in junction temperature of IGBTs, thereby causing damage to IGBTs. Consequently, the research on IGBT reliability technology is conducted in this paper, not only for the reliability improvement, but also for the cost reduction. Firstly, mission-profile-based lifetime prediction of IGBT modules in urban rail transit train traction converters is carried out. Then, the effect of control approach for traction converters on IGBT lifetime is analyzed. Last, the reliability-oriented traction converter control strategy is studied, which will improve the reliability and availability of traction converter.
