Robust, Low-Loss RCIGCT Technology and MV Applications

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 range from 1000Arms up to 3500 Arms. Future bi-mode BGCT technologies will enable even higher currents without any parallel connection up to 5000 Arms. The ceramic presspack housing of the RCIGCT in combination with the IGCT clamp network allows a unique and safe plasma containment in all fault cases. Future high power MV application like pumped hydropower, MVDC collection grids for renewables, interties for distribution grids and future MVDC distribution backbones can be served at leading costs and efficiency levels. The low-loss RCIGCT technology is inherently a future option at higher voltage levels, i.e. in HVDC applications.
