On the Current Sharing Control of ITER Poloidal Field Converter

摘要

Current sharing control is used to assure the stability of unbalanced current between two paralleled bridges when International Thermonuclear Experimental Reactor poloidal field converter operates in parallel mode. This paper, based on the equivalent model of current sharing circuitry, describes the dynamic behavior of current sharing control by means of frequency and time domain methods. A control strategy is proposed and simulations are performed to verify the effectiveness of the proposed strategy in current sharing control.
