摘　　要：针对超导托卡马克核聚变实验装置(Experimental Advanced Superconducting Tokamak,简称EAST)对等离子体位移快控电源大电流快速响应要求,采用多组逆变单元并联运行。分析了采用均流电抗器形式的逆变电源并联产生环流的情况,根据EAST快控电源系统的设计要求,对逆变单元采用电流闭环调节器控制,可有效提高系统对低频和直流环流的抑制能力。实验结果说明该系统设计方案合理,控制策略有效。The method of multiple inverters paralleled is presented to meet the need of large current and fast control for the plasma displacement power supply in the experimental advanced superconducting Tokamak（EAST）.The circulating current among paralleled inverters with current sharing reactor is analyzed.According to design demand of EAST fast control power supply,the adjuster of current close loop is applied to inverter,which can advance ability to restrain loop current in low frequency and DC output.The experimental results confirm the validity of proposed scheme and control strategy.
