EAST纵场电源由两组双反星形整流电路并联而成,两组电源的环流必须满足其要求.从纵场电源数学模型着手,通过电路分析,得到环流和电源参数、均流控制器参数的关系式,再依据此关系式和环流的要求设计出相应的均流控制器参数.理论分析和实验结果表明,这种利用电路分析设计出均流控制器的方法.对于并联电源系统参数的设计具有一定的指导意义.

The toroidal field power supply(TFPS)of EAST is consisted of two groups of 6-pulse midpoint converters with parallel-connection,so the appropriate current-sharing method is provided to restrict their circulating-current.Based on the maths model of TFPS and the circuit analysis,the circulating-current formulas are presented,which indicate the relations between the circulating-current and TFPS parameters,current-sharing controller parameters.According to the formulas and the requirements of circulating-current,the current-sharing controller parameters are designed.The experiment proves that the circulating-current can be limited as its requirements by this scheme.The method is also applied to the other power supply with parallel-connection effectively.
