Abstract

The high power bi-directional DC thyristor switch is one of key equipments of the poloidal field power supply system in EAST Super-conductive TOKAMAK. Forced commutation technology has been analyzed thoroughly, which is the base of DC thyristor switch. Firstly, the reliable turn-off criterion and optimized expressions of parameters have been derived. Then, the influence of distributing resistance has been emphasized during turn-off. At last, a series of tests result have been provided. All these work make sure development of high power bi-directional DC fast thyristor switch finished successfully.
