Abstract : Simulation tools are playing prominent roles in the engineering design applications. By using the simulation tool IGBT parameters can be tuned and that can be used in the modelling of inverter. A good IGBT model will help us in calculating the Electric Drive (which consist of battery, inverter, and electric machine along with control) dynamics with better accuracy. To evaluate efficiency of inverter, IGBTs need to be validated as per datasheet specifications. In this study, initially IGBT�s used for modelling are validated, tested in simulation environment and further used for investigation. With math works provided IGBT in fixing the parameters as per data sheet, some parameters which needs to be filled additionally in IGBT block are taken as default for every data sheet which does not provide good response. So, for finding the unknown parameters certain standardized procedure should be followed. Simulink optimization design tool is used for parameterizing the IGBT specifications taken from the data sheet. A standard IGBT test circuit model is developed in Simulink and tested for IGBT characteristics from data sheet. In this paper by using Simulink design optimization tool the results are validated between the simulated characteristics w.r.t the data sheet characteristics.
