Abstract:

The voltage spike, current spike and power loss in switching process is important factors in reliability of insulated gate bipolar transistor (IGBT). The real time simulation of IGBT is studied in this paper, taking the basic cell of IGBT power electronic circuit as an example. The function model of IGBT for real time simulation is built by piecewise interpolation method, in which the parameters are get from the datasheet. The real time simulation of IGBT is realized in field programmable gate array (FPGA), and the results can reflect the key performances of switching process.
