A SPICE IGBT Model with easy parameters extraction

An accurate IGBT model is presented in this paper. It is based on the IGBT physical structure. The model uses an equivalent circuit which combines a MOSFET, controlled by a voltage-controlled voltage source, in series with a diode. the required parameters can be extracted with a simple procedure from the datasheet dc characteristics given by the manufacturers. The results of the comparison between the simulation and the datasheet information shows an average error less than 9% for the output characteristics and less than 7% for the transfer characteristic. Moreover, the model is simple and can be implemented in any SPICE-based circuit simulator. A description of the model and the parameter extraction procedure will be provided along.
