IGBTs are the most preferred power devices in medium power and frequency applications. Due to rapid developments of IGBT technology, the need of more accurate and reliable compact models within circuit simulators has become crucial for both device and circuit designers. Thus, an improved and optimized version of the Kraus NPT IGBT model has been developed and implemented within PSpice OrCad environment. The enhancements brought to the model have regarded the addition of some IGBT typical features such as PiN injection effect or avalanche breakdown as well as the definition of temperature dependencies of semiconductor physical constants to make model suitable for electro-thermal simulations. An automated parameters calibration procedure, based on curve-fitting method and implemented in MATLAB environment, has been proposed for definition of model parameters. Hence, the ET model has been validated by comparing simulation results with experimental measurements performed on laboratory test circuits of three different application scenarios. Finally, the Kraus model has been extended to modern Field-Stop IGBT technology by implementing in PSpice the approximated equations of FS layer.
