Performance of a 4.5 kV, 100 A current-scalable emitter turn-off (ETO) thyristor module

This paper highlights the experimental development and demonstration of an ETO module based on planar GTO technology that is well-suited to be scaled for a multitude of current requirements, with continuous current ratings from 100 A, and voltages up to 4.5 kV. The ETO module has low on state voltage drop and good snubberless turn-off capability. Different from press-pack ETO design, the ETO module employs industry standard module design widely used in IGBT module. Moreover, the ETO module has forward biased safety operation area (FBSOA), so it can achieve di/dt control and short circuit protection capability.
