摘　　要：在HT-7托克马克实验装置上DNB系统实验中,加速机高压电源系统的储能电容器组充电电压有过冲现象,为了能够分析并解决这一问题,详细介绍了该套加速极高压电源系统的组成、结构、工作原理以及初级高压充电电源系统的组成、结构和控制流程等,对实验中的过冲现象行了监测,利用具体的电路模型对初级高压充电电源进行了研究,经过详细的分析和计算,结果表明由于变压器漏抗的影响,使得电容器组上随着充电电压设定的不同有0～6 kV的过冲,因此可以认为变压器漏抗是造成电容器组充电过冲的最主要原因,采用反馈控制和简单的预测控制方式,很好地解决了这一问题。A high voltage power supply system has been developed for the diagnostic neutral beam on the HT-7 experimental Tokomak,and the over-voltage phenomenon of storage capacitor was founded in the experiment.In order to analyse and resolve this problem,the structure and principle of high voltage power supply is described and the primary high voltage charging power supply system is introduced in detail.The phenomenon of over-voltage on the capacitors is also studied with circuit model,and the conclusion is obtained that the leakage inductance is the mAin reason which causes the over-voltage on the capacitors.
