Abstract

The emitter turn-off (ETO) thyristor is a new type of MOS-controlled thyristor that has a wide reverse-biased safe operation area (RBSOA) due to its unity-gain turn-off capability. Because of the negative feedback provided by the emitter MOSFET, the ETO also has current saturation capability. The forward biased safe operation area (FBSOA) of a small ETO is experimentally demonstrated. The results show that the small ETO has excellent current saturation capability that can be used to control the turn-on di/dt. Issues related to realizing a large area ETO´s FBSOA are discussed
