The fault characteristics of IGBT open-circuit signal are unstable and the fault sample types are unbalanced, which leads to the inaccuracy of IGBT open-circuit fault diagnosis. Therefore, two unbalance IGBT open-circuit fault diagnosis methods based on 1D-CNN and 2D-CNN are proposed. The experiment...
