Evaluation of Switching Loss and Imbalance in Multi-Element Power Modules
The purpose of this paper is to analyze the switching behavior with variations in element characteristics using FEM model of power module with multiple elements, investigate the load on each element and the resulting energy loss, and evaluate the cause. The authors performed circuit simulation based on the actual model and calculated the switching loss from the result. Based on this, they examined the analysis conditions in electro-thermal kneading analysis and conducted FEM analysis.
