4MeV离子静电加速器稳压控制系统设计

Brief introduction about a design for 4MeV ionelectrostatic accelerator stablizing voltage system

本文首先介绍了4MeV正离子静电加速器的稳压原理,然后与其他几种稳压方式相比较,最终确定了旋转伏特计法。之后设计了工频陷波器、低通滤波器、精密镇流滤波器、带通滤波器、误差放大器等。经过上述电路的处理,能够输出0~10V的控制信号,用来控制电晕针放电。实测结果表明,采用该电压稳定控制系统在长时间运行的情况下,能够确保终端电压稳定在一个恒定的水平(电压稳定度小于1%)。

Firstly,a voltage stabilizing principle of 4MeV accelerator was introduced. After comparing with some other stabilizing methods,finally generating voltemeter(GVM)was used in this stabilizing system.The circuit consistutes of a notch filter,a pass-filter,a rectifier filter,a band-filter and an error amplifier was designed and made.The out put voltage of the controlling circuit was set to 0-10 V which controlled the corona discharge current.The instability of the terminal voltage is tested to be less than 1 %.
