摘要
研制了兰州重离子加速器深层治癌脉冲开关电源,阐述了双闭环的控制原理,给出了电流环与电压环的开环伯特图。进行了仿真,并在1台电源上进行了比较研究和试验,电流误差与单电流环脉冲电源相比明显减小。对测试结果进行了分析,表明主电路结构和双闭环控制方案是切实可行的。
The pulsed switching power supply was developed for deep tumor therapy facility with heavy ions in cooler-storage-ring of the heavy ions research facility in Lanzhou (HIRFL-CSR). The control principle of the dual closed-loop scheme was described and the open-loop Bode diagrams were given. The results of simulation and prototype experiment show that the current error gets much smaller than that of the single closed-loop pulsed switching power supply. Moreover, the simulation and test results were analyzed, and the circuit configuration and dual closed-loop strategy select- ed are practicable.
