Inhalt:
Four inch thyristor in the package with 100 mm pole piece was developed and fully qualified for 8.5 kV voltage class. The maximal ON-state voltage has been reduced from VTmax = 1.95 V to VTmax = 1.70 V at IT = 1.5 kA and T = 90 °C. Significant reduction of leakage current extended the blocking stability up to 115deg C. The device proved its robustness and lowered losses during valve testing in 6-pulse back-to-back synthetic test circuit. The reduction of valve losses is estimated at 6 to 8 %. The 3rd Generation of PCTs for HVDC from ABB is established.
