摘　　要：在不降低系统动态性能的情况下,为提高托卡马克装置中性束注入(NBI)加速极高压电源的输出精度,介绍了一种基于数字控制PWM-PSM模块。在分析电源模块的运行条件后,重点讨论了变换器拓扑结构、电路参数及数字控制策略。随后对电源系统进行了仿真分析,同时在EAST装置中进行了验证。运行结果表明,该电源模块能够很好地解决NBI高压电源系统动、稳态性能之间的矛盾,满足了EAST装置的运行要求。Discussions focus on the design considerations of digital control PWM-PSM module,which is used to improve output voltage precision of the high voltage power supply for the acceleration grids of the neutral beam injectors（NBI） of Tokamak under the condition without reducing system dynamic performance.Firstly operating conditions are analyzed,then topological structure,circuit parameter and the digital control method are discussed,on the basis of that the whole power system is simulated,the given PWM-PSM Modules are used to operate in the high voltage power system of the NBI of the EAST.The experimental results show that the PWM-PSM module can solve conflicts between steady performance and dynamic performance of the high voltage power system,and also can be able to meet the require-ments of the EAST,which is an advanced full super-conducting Tokamak device.
