Abstract
This paper investigates the operation of ITER(International Thermonuclear Experimental Reactor) Vertical Stabilization(VS) converter with circulating current. The VS converter has two subunits in parallel. The subunit is composed two back-to-back 12 pulse thyristor converter in series. The circulating current free technique can not always maintain the closed path for the load current because of a dead time zone of the converter operation at the region of the load current inversion. The complex circulation current technique for the load current inversion with VS converter can achieve the fast response and always maintain the closed path for the load curret. The paper proposes the new circulating current algorithm for the load current inversion of ITER VS converter and proves the performance of the circulating current technique with PSIM simulation study.
