摘　　要：上海同步辐射装置数字化电源的开发主要是采用完全数字化PWM直接控制功率管IGBT的数字控制器,利用LabVIEW平台开发了数字电源的监控程序,通过串口通讯(R232)进行监控,友好、清晰的人机界面能够方便监测数字电源和修改它的控制参数。并基于LabVIEW编写的另一个虚拟仪器程序通过高精度的Keithley仪器和计算机实现该数字电源的电流长期稳定性测试和记录,Excel格式数据存储通过该程序完成,可以为以后进一步分析做准备。During development of the Shanghai Synchrotron Radiation Facility （SSRF） digital power supply, a digital pulse-width modulator （PWM） directly controls the power circuit insulated gate bipolar transistor （IGBT）. A program in LabVIEW language has been developed to perform computer control and monitor for the digital PS via serial communication （RS232）. The program provides a friendly user interface to the digital PS that makes it easy to observe its behavior and modify its parameters. Another program, also in LabVIEW language, has been developed to test long term stability of the digital power supply and store the experimental data via extremely precise Keithley instrument and computer. The experimental data are stored in an excel file which can be processed and analyzed in the future.
