N2 - Most of the failures in IGBTs are caused by thermal fatigue. Hence, the thermal analysis of IGBTs for each particular application is an important step in determining their lifetime. In this paper, the thermal analysis of a STATCOM is presented for two different applications, power factor correction and harmonic elimination. The STATCOM model is developed in EMTP for the above mentioned functions. The analytical equations for average conduction losses in an IGBT and a diode are derived. The electrothermal model is used to estimate the temperature of the IGBT. A comparative analysis of the thermal stresses on the IGBT with various parameters such as power factor, harmonic frequency, and harmonic amplitude is presented as a basis for future reliability testing of IGBTs in FACTS applications.
