Mixed-mode Circuit and Device Simulations of IGBT with Gate Unit Using Synopsys Sentaurus Device

Abstract: The use of simulation tools is of great value in the process of developing new powerelectronics devices and new converter topologies. The development time of powerelectronics and converter topologies can be shortened by the use of simulation tools.Sentaurus Device combines a good numerical model of power electronics devices andcomplex external circuits. It’s capable to simulate the IGBT switching behavioursapplying different gate unit settings in HVDC Light™.The numerical model of the IGBT is studied in the thesis. The results of the IGBTfine-tuning are carried out. Implementing the IGBT model with its gate unit circuitusing Sentaurus Device, the impact of various gate drive settings on the IGBTswitching losses is demonstrated.
