摘要

摘要: 高压电源是中性束注入加热系统的重要组成部分，决定着束能量和引出束流的品质。为满足HL-3装置中性束注入系统功率需求，设计了基于PSM技术的模块化高压电源系统，通过串联叠加若干电源模块，实现额定电压输出。电源模块采用单相桥式整流和半桥输出控制，设计了软启动电路和泄能回路，实现电源模块在市电供电条件下进行功能测试；设计调节模块电路，通过控制调节模块的输出电压等级，实现对电源输出电压的精确控制。利用MATLAB中Simulink工具箱对电源模块及系统进行仿真测试，测试了电源的软启动功能、额定输出及短路保护性能。搭建1 600 V/50 A/5 s试验样机和80 kV/50 A/5 s测试平台，实验验证电源系统模块电气性能。经仿真和实验验证，电源模块试验样机满足额定输出要求，通过串联叠加，实现80 kV电压稳定输出。电源短路保护时间小于6 μs，实现了快速保护关断，满足HL-3装置5 MW中性束注入系统对高压电源的性能要求。

Abstract: The high voltage power supply is an important part of the neutral beam injection heating system. It determines the beam energy and the quality of the extraction beam current. To meet the power demand of the neutral beam injection system of the HL-3 device, a modular high voltage power supply system based on pulse step modulation technology is designed, and it can achieve the rated voltage output by connecting power modules in series. Each power module uses a single-phase bridge rectifier and half-bridge output control, and a soft start circuit and an energy discharge circuit are designed so that the power supply module can carry out function tests under the condition of utility power supply. The regulator module circuit is developed to realize the precise control of power supply output voltage by controlling the output voltage level of the regulator module. The power supply module and system are simulated using the Simulink toolbox in MATLAB, and tests of the soft start function, rated output and short circuit protection performance of the power supply are carried out. By building a 1600 V/50 A/5 s test prototype and a 80 kV/50 A/5 s test platform, the electrical performance of the power system module hasbeen experimentally verified. The simulation and experimental results show that the power module test prototype meets the rated output requirements and can stably realize 80 kV voltage output through series connection. The short circuit protection time is less than 6 μs, which can realize fast protection shutdown of the power supply and meet the performance requirements of the HL-3 device 5 MW neutral beam injection system for the high voltage power supply.
