Segmental Degradation RUL Prediction of IGBT Based on Combinatorial Prediction Algorithms

IEEE Access, 2022
Aiming at the segmentation nonlinear degradation characteristics of IGBT, the traditional single remaining useful lifetime (RUL) method has low accuracy. This paper proposes a method combining gray prediction and particle filter algorithm. The gray prediction model is used for slow degradation trends prediction in the early stage.
