摘要:
为了实时评估机车运行时IGBT 的结温水平并为IGBT 健康状态和寿命预测提供依据,提出了一种利用现场实测变流器输出电流和相电压数据、基于开关周期平均损耗法的实时结温计算方法,开发了相应的结温计算程序,并与建立的PLECS 电热仿真模型计算结果进行了比较,结果表明该方法能准确计算不同工况下的结温。该方法不仅能方便地计算出该工况下的结温,且无载荷点数量的限制,无需知晓PWM 控制策略参数,非常适合变流器现场不同运行工况下的结温计算。
Abstract:
In order to evaluate IGBT operation junction temperature of locomotive operation and provide the basis for IGBT health status and life prediction, a real-time junction temperature calculation method was proposed based on the average power loss of each fundamental period from output phase voltage and current of converter. A corresponding calculation program of temperature junction was developed, and performance of the proposed method was compared with PLECS electro-thermal simulation. The results showed that the proposed method not only can calculate junction temperature of different conditions accurately, but also can calculate junction temperature conveniently without knowing parameters of the control strategy and quantity limitation of loading cycles, and it is suitable for IGBT junction temperature calculation with different operation working conditions of converter in engineering application.
