摘　　要：为了开展高参数物理研究,研制了满足脉冲发电机组、电网供电需求的长脉冲开关电源模块及控制系统。电源模块通过改变交流接线端接线方式进行模块供电类型切换,通过内置的软启电路减小模块充电过程中浪涌电流冲击对电网及开关的影响,模块控制器满足两种运行方式下的保护、驱动、状态监测设计需求。控制系统采用单片机及可编程逻辑门阵列架构,具有液晶屏本地/上位机远程两种控制功能。在单片机中采用集成电路总线扩展IO的方式实现软启控制、监测功能,减少数据传输链路及系统的复杂性;在可编程逻辑门阵列中实现电源的控制算法,并通过电平信号转换处理,统一了光电转换箱接口设计。在搭建的测试条件下测试结果表明,模块及控制系统设计满足要求,电源实现80kV/100s/20A输出参数测试及保护实验测试。To conduct high parameter physics research,a long pulse switching power supply module and control system were developed to meet the power supply needs of pulse generator sets and power grids.By changing the wiring method of the AC terminal,the module power supply type can be switched.The built-in soft start circuit can reduce the impact of surge current on the power grid and switches during the module charging process.The module meets the design requirements for protection,driving,and status monitoring under two operating modes.The controller adopts a microcontroller and programmable logic gate array architecture,with both local and remote control functions.It implements soft start control and monitoring functions in microcontrollers by using integrated circuit bus to expand IO,reducing the complexity of data transmission links and systems;The control algorithm of the power supply is implemented in the programmable logic gate array,and the interface design of the photoelectric conversion box is unified through level signal conversion processing.The test results under the established testing conditions show that the module and control system design meet the requirements,and the power supply achieves 80 kV/100 s/20 A output parameter testing and protection experiment testing.
