摘要：
The superconducting toroidal field (TF) plays an important role in a superconduct-ing tokamak,whose power supply was developed based on the feedback control principle.In this paper,superconducting tokamaks in different countries are described,and the TF power sup-ply of the International Thermonuclear Experimental Reactor (ITER) is taken as an example to study the current-sharing characteristics in the current-stabilized stage.Firstly,the math-ematical model of the TF power supply is established,and then the 3-loop control method is put forward for achieving the stability and reliability of current-stabilization and current-sharing.Furthermore,further studies indicate that the current-sharing controller has no influence on the current-stabilized control,and current-stabilizing and current-sharing can be realized at the same time.All the work done provides valuable references for the current-sharing design of the TF power supply for a superconducting tokamak,and all these studies lay a solid foundation for developing superconducting tokamaks.
