摘要
集成门极换流晶闸管(IGCT)是保障大功率牵引变流器高效可靠运行的重要元件。IGCT器件开关过程中电压及电流的动态特性极大地影响了大功率变流器系统的稳定运行。研究了不同测试工况对4.5kV/4 kA的IGCT器件动态特性参数的影响,并提出了一种考虑器件电压、电流和温度的IGCT器件损耗数值模型。该模型形式简单、易于实现、具有可推广性,为进一步分析大功率变流器系统损耗及效率特性打下理论基础。
The integrated gate commutated thyristor(IGCT)is an important element for efficient and reliable operation of high power traction converters. The stability of high power converter system is significantly affected by the voltage and current dynamic characteristics of the IGCT device during the turn-on and turn-off processes. The dynamic characteristics parameters of the 4.5 kV/4 kA IGCT device were studied,which were tested under different testing conditions. Furthermore,a numerical loss model of the IGCT device in terms of the voltage,current and temperature was presented. The model is apt to be implemented and extended because of its simple form,and a theoretical basis for the analysis of the loss and efficiency characteristics of the high power converter system is established.
