This paper proposes a junction temperature estimation method for IGBT power module in three-phase inverter through coupling the temperature-corrected power loss calculation model and Foster thermal model. Considering the structural characteristics of IGBT, the loss calculation model is established with full study about the influence rule of temperature, gate resistance and other factors on the loss...
This paper presents an electro-thermal based junction temperature (Tj) estimation method of insulated gate bipolar transistor (IGBT) power module. Firstly, the internal structure of IGBT and its transient characteristics are researched, through which the factors affecting the power loss as well as its basic influence rule are analyze and the multivariable loss calculation model is obtained. And then...
