A Performance Optimized CSTBT with Low Switching Loss [PDF]
Micromachines, 2023 A novel Performance Optimized Carrier Stored Trench Gate Bipolar Transistor (CSTBT) with Low Switching Loss has been proposed. By applying a positive DC voltage to the shield gate, the carrier storage effect is enhanced, the hole blocking capability is improved and the conduction loss is reduced.

Ninth IEEE International Pulsed Power Conference, 1993 Abstract : Our experiments show energy losses between 2 and 10 times that of the resistive time predictions. The experiments used hydrogen, helium, air, nitrogen, SF6, polyethylene, and water for the switching dielectric. Previously underestimated switch losses have caused overpredicting the accelerator outputs.

Analytical Calculation of the Residual ZVS Losses of TCM-Operated Single-Phase PFC Rectifiers
IEEE Open Journal of Power Electronics, 2021 Triangular-current-mode (TCM) modulation guarantees zero-voltage-switching across the mains cycle in AC-DC power converters, eliminating hard-switching with a minor ${\approx} {30}{\%}$ penalty in conduction losses over the conventional continuous ...
