Reverse Blocking Capability of Symmetric SCRS at High Current and High Voltage Reversals

Abstract

Symmetric thyristors with. blocking voltages of 2.5 kV have been evaluated under high current conditions in circuits where a reverse voltage is applied to the SCR, caused by a load mismatch in the pulse forming network. The 50 mm diameter SCR was operated in a 45 m omega PFN with a 12.5 m omega load and a shorted load. The peak Current switched with the 12.5 mn load at 1.5 kV was 25.2 kA.
