摘要

介绍了一种电流闭环控制扫描电源的实现方法

主电路采用四象限变换器拓扑结构

高频调制波在负载电感作用下

输出低频扫描电流

达到给励磁线圈供电的目的。由于采用负反馈技术

输出电流将严格跟踪参考波形

从而有效抑制磁铁参数、环境变化等因素对扫描电流的影响。参考波形是一个可编程波形

能实现扫描电流和加速器的最佳匹配。本文研制了一台扫描频率15 Hz、峰值电流±14A的扫描电源

并成功应用于地纳米加速器上。

Abstract

In this paper

a four-quadrant converter topology and the current closed-loop feedback technology are used to realize the scanning magnet power supply.The reference waveform is modulated by high frequency

which is then filtered by load inductance.The output current can be set by any programmable waveform within certain bandwidth.As a result of the current close feedback

the load current is not affected by magnetic parameters and environment changes.A 15 Hz with 12 A scan power supply has been developed and the test results are given.
