Thermal model of power semiconductor devices for electro-thermal circuit simulations

An electro-thermal (ET) strategy used for ET circuit simulations is described in this paper. An original program for a MATLAB environment based on a deconvolution method is written and used for a determination of the RC dynamic thermal network parameters. An excellent agreement is obtained between experimental thermal transient response function of the device for a step function excitation and simulated one obtained using corresponding RC thermal network.
