Automated vertical design co-optimization of a 1200V IGBT and diode

In this work, we concentrate on extending our optimization method for IGBTs [1] in drives applications by incorporating diode parameters in addition to IGBT parameters. For this purpose, the fabrication process of the diode, including a platinum diffusion and it's parameters for lifetime adjustment [2], was added to the optimization loop. Consequently, the simulation of an IGBT turn-on event in the optimization loop was required.
