摘要
高压电源是中性束加热用离子源束流引出的关键设备,其运行参数和性能直接决定引出束粒子能量和离子源引出效率。为了进一步提高中性束离子源实验平台高压运行参数和性能,重新优化设计并研制了80k V/50A高压电源的所有模块。首先介绍了80k V/50A高压模块电源的主电路拓扑结构和电源模块,运用仿真软件对高压电源主回路进行了充放电、打火保护仿真,仿真结果符合设计要求。最后,通过调试实验发现了电源模块存在空间绝缘不足、整流桥击穿、触发控制不响应等问题,进行了分析优化改进,完成了80k V/50A高压模块电源的升级研制。
The high-voltage power supply is the key equipment for the ion source beam extraction for neutral beam heating.Its operation parameters and performance directly determine the energy of the extracted beam particles and the extraction efficiency of the ion source.In order to further improve the high-voltage operation parameters and performance of the neutral beam ion source experimental platform,all modules of the 80kV/50A high-voltage power supply were re-optimized and developed.This article first introduces the main circuit topology and power module of the 80kV/50A high-voltage module power supply.The main circuit of the high-voltage power supply is simulated using simulation software,and the simulation results meet the design requirements.Finally,through debugging experiments,it was found that the power module has insufficient space insulation,rectifier bridge breakdown,and trigger control unresponsiveness.The analysis and optimization were carried out.Finally,the upgrade and development of the 80kV/50A high-voltage module power supply was completed.
