| Abstract |
Loss-optimized turn-off strategies for modern 'low-saturation' IGBTs are considered in this paper. TCAD turn-off simulations of the considered approaches reveal the possibility of substantially reducing the turn-off energy losses for such a low saturation IGBT model. An FPGA-based gate driver is implemented and turn-off measurement results with the two-step feedforward-based desaturation pulse method are provided. These results have shown up to a 24\% reduction in turn-off energy losses for this most basic approach. Simulation results with various approaches are provided and these show a potential reduction of up to 50\% in turn-off energy losses. |
