首发时间:2014-01-02
摘要:随着IGBT应用日趋广泛,对于IGBT的视情维修需求也日趋紧迫。本文基于粒子滤波理论,提出一种IGBT的寿命预测方法,通过温度循环实验获取退化参数通态压降VCE的动态变化,使用Matlab工具箱对退化参数寻找拟合模型,并通过将该模型与粒子滤波算法结合运用,对IGBT的剩余使用寿命进行预测。结果表明,所提出的预测方法能够以较高的预测精度实现对被测器件的剩余寿命预测。

Particle Filter Approach for IGBT Remaining Useful Life
Abstract:With the increasingly widespread application, the requirement for PHM of IGBT is becoming gradually urgent. Based on particle filter theory, a method for remaining useful life(RUL) prediction of IGBT is proposed. Firstly, the deterioration parameters on-state VCE and ICE are extracted by temperature cycling test, then a model is developed based on the degradation trend exhibited by deterioration parameters. In the end, PF approach is applied to the IGBT's RUL prediction with the mentioned model. The results show that the proposed prediction method can achieve a high prediction accuracy.
