Research on the test scheme of fault suppression capability for ITER PF converter

Fault suppression capability (FSC) test with DC short downstream DC reactor of international thermonuclear experimental reactor (ITER) poloidal field (PF) converter is performed to verify the thermal stability characteristics of the converter bridge arms. In this paper, firstly, DC short downstream DC reactor of ITER PF converter is analyzed to get the fault current. Then, the appropriate test scheme is designed and the feasibility of the test scheme is verified by simulation based on test platforms in Institute of Plasma Physics, Chinese Academy of Science (ASIPP). Finally, the effectiveness of the designed test scheme results are verified by the test platforms in ASIPP.
