Integrated Gate Commutated Thyristor: From Trench to Planar [PDF]
2020 32nd International Symposium on Power Semiconductor Devices and ICs (ISPSD), 2020 The planar Integrated Gate Commutated Thyristor (IGCT) concept is proposed to simplify the fabrication process of the device and improve the ruggedness as well as electrothermal performance of the device. The planar IGCT concept has been verified experimentally with 4.5kV devices fabricated on 4-inch Si wafers.

Physics‐based compact model of integrated gate‐commutated thyristor with multiple effects for high‐power application [PDF]
IET Power Electronics, 2018 This study presents a physics‐based compact model of the integrated gate‐commutated thyristor (IGCT) with multiple effects for the high‐power application. The proposed model has both acceptable accuracy and computation time requirement, which is suitable for system level circuit simulation and IGCT's whole wafer modelling work.
