This paper presents the design modifications and improved technology trade-off performance of the high voltage Reverse Conducting-Integrated Gate Commutated Thyristor (RC-IGCT), which is designed and manufactured to be used in demanding high voltage applications for dc-link voltages of up to 5.3 kV. This paper also presents the cosmic ray hardiness of this device. Furthermore, it presents the system level simulations to evaluate the maximum possible output current over the speed range of the drive using three level neutral point clamp (3L-NPC) topology.
