Current sharing among multi-parallel thyristors is a key task in the design of high-current converters. However, conventional current sharing methods seldom consider the stray inductance which acts a significant role in the current sharing. This paper mainly focuses on stray inductance, and builds a current sharing equation based on Partial Element Equivalent Circuit (PEEC) method for the current sharing analysis and design of high-current converters. The deduction of the equation is presented. As an example, the application of the proposed method in the design of the International Thermonuclear Experimental Reactor (ITER) Poloidal Field Converter Unit (PFCU) is briefly presented. The current sharing coefficient is over 0.8, which is greatly improved and beyond the required value. The method proposed in this paper can be used for the fast design of the physical layout of a converter, and further improve its current sharing along with conventional design methods.
