IGBT advanced model used on degraded mode analysis

The study of the degraded mode is of high importance in proposing diagnosis strategies. Hence the use of a precise modelling of the power electronic components is necessary to make good simulations. The paper presents an advanced IGBT model based on the functional description of a complete model which covers linear, saturation and breakdown modes. Several simulations are presented to show its validity in the static and dynamic behaviours. The comparison between the Matlab Power Blockset model and the proposed one proves the reliability of our approach.
