Several IGBT model proposed and constructed over the past years have exposed different essential qualities. However, in this paper, a new model of IGBT and Freewheeling diode based on electrical behavior is presented. The proposed parameters extraction process adopts the least squares regression and bilinear interpolation and, a two-level capacitance technique. and the model’s structure solely consists of fundamental components. In addition, the proposed model validates its simplicity for parameters extraction process, and its user-friendly application for a circuit topology of fundamental components. Some key factors of our proposed model are; independent time constraint, implementation flexibility, easily application by different topologies. These enumerated factors reinforce the reliability and suitability of our proposed model for a circuit simulation and optimization. The verification of our proposed model was steered with the use of an experimental circuit that consists of commercial components. Lastly, our simulation results showed a pattern of consistency with the experimental results.
