As the power density and switching frequency increase, thermal analysis of power electronics system becomes imperative. The analysis provides valuable information on the semiconductor rating, long-term reliability and efficient heat-sink design. In this paper, the thermal model and thermal distribution of discrete Insulated Gate Bipolar Transistor with non heat-sink and heat-sink has been studied. For analysis of thermal distribution, we obtained results by using finite element simulator, ANSYS and compared with experimental data.
