In the automotive applications, especially in traction inverters for electrical vehicles, high power, efficiency, and reliability are fundamental targets. In this paper, an optimized layout of SiC-based power module able to limit the positive and negative transient gate-source voltages is proposed. The module design and features are firstly described, then SPICE-SIMetrix simulations on a layout without optimization are shown. Moreover, a description of the necessary guidelines to cope with transient negative and positive overvoltages phenomena is outlined. Finally, simulation test results on the optimized module layout are presented.
