The parameters identification and validation for IGBT based on optimization algorithm

Abstract

IGBT (Insulated Gate Bipolar Transistor) is becoming more and more popular in many power applications, since it offers a good compromise between on-state loss, switching loss and easy of use. To develop circuits and systems using theses devices, model and model parameters are needed for use in circuit simulations. This paper presents a procedure for identifying the most IGBT models parameters. As an example, the results of identified parameters of BUP302 are given. Based on the identification, the paper presents the method for parameters validation. At last, the conclusion was given.
