2019 10th International Conference on Power Electronics and ECCE Asia (ICPE 2019 - ECCE Asia).
The combination of the robust low-loss RC-IGCT technology with the modular multi-level converter (MMC) technology is a key enabler for high-power MV applications from 50 to 500 MV A. The RCIGCT technology covers cost-efficiently phase currents in the

2017 19th European Conference on Power Electronics and Applications (EPE'17 ECCE Europe).
A large area (150mm) high voltage (6.5kV) Reverse Conducting-Integrated Gate Commutated Thyristor (RC-IGCT) has been developed for low frequency high power electronics applications. The devices were fabricated with GCT to diode active area ratio of 1
