摘　　要：紧凑环注入(CTI)技术是聚变装置实现堆芯加料的有效手段,为实现CTI设计了一套大电流、高重复频率脉冲电源系统。对等效后的RLC二阶放电电路进行集总参数计算公式推导,得出了放电电流峰值、半波周期等关键参数的计算公式,并设计了四路脉冲电源的基本参数;进一步进行了参数建模仿真,给出仿真波形和结果参数。对关键的放电开关器件进行分析选型,并设计电源低感安装结构。在全超导托卡马克紧凑环注入装置(EAST-CTI)上对电源进行了放电测试,通过远程控制软件灵活设置参数和控制电源的工作时序,实际放电波形、输出电流参数与理论计算和仿真吻合性好。电源系统的峰值电流超过300kA,重复频率为2Hz,这表明所设计的电源系统可以有效地应用于紧凑环注入装置,并具有良好的工程实用价值。Compact torus injection(CTI)technology is an effective means to realize core fueling in fusion device.A set of high current and repetition rate pulse power supply system is designed to realize the CTI.By deducing the lumped parameter calculation formula of the equivalent RLC second-order discharge circuit,the calculation formula of key parameters such as the peak value of discharge current and half wave period is obtained,and the basic parameters of the four-way pulse power supply are designed.The parameters are modeled and simulated,and the simulation waveform and the result parameters are given.The key discharge switch components are analyzed and selected,and the low-inductive installation structure of power supply is designed The discharge test of the power supply was carried out on the full-superconducting tokamak-compact torus injection device(EAST-CTI).The remote control software was used to flexibly set parameters and control the working time sequence of the power supply.The actual discharge waveform and output current parameters were in good agreement with the theoretical calculation and simulation.The peak current of the power supply exceeds 300kA and the repetition rate is 2Hz,which indicates that the designed power supply system can be effectively applied to the CTI device and has good engineering practical value.
