摘　　要：高压脉冲电源是中性束注入加热装置中的主要系统之一,该电源具有输出电压0～100kVDC可调,最大电流100A,电压调整精度<1%,纹波(峰-峰)<2%,电流上升时间≤20μs,关断时间≤5μs等特点。控制系统的好坏将直接影响电源的运行,为此,主要研究了基于数字信号处理器(DSP)和复杂可编程逻辑控制器(CPLD)的高压脉冲电源的控制系统,CPLD可实现电源模块内部故障信号逻辑运算、绝缘栅双极晶体管(IGBT)和晶闸管(SCR)的分合;DSP主要实现与上位机的光纤通信。通过60kV/100A实验及测试的结果表明,该控制系统是可行的。High voltage pulse source is the most important system of neural beam inject （NBI） equipment. The voltage source has the characteristics as follows： output voltage can adjust from 0 to 100 kV, the biggest current is 100 A, the voltage accurate is less than 1%, ripple less than 2%, current rise time is not more than 20μs and the turn off time is not more than 5 μs. so, the control system is the key to the NBI. We investigated the control system which was based on the DSP and OPLD. CPLD was used for Boolean calculation, turn on/off IGBT and SCRI DSP was used to communicate with remote PC. The 60 kV/100 A experiment proves the control system is available.
