Abstract

The current sharing of bridge arm is very important for the design of external bypass, which provides protection for the ITER poloidal field converter and magnets in fault conditions. Thyristors in parallel should withstand short peak current for each arms. In this paper, the method based on inductance matrix is presented. After theoretical analysis and simulation, the prototype has been manufactured by China industry. The test results on the prototype show that the current sharing performance of the prototype can fully satisfy the design requirement.
