摘要
介绍了一种扫描磁铁电源的改进方案,在传统的非线性近似系统的基础上进行了改良,在全桥对称电路上采用了一种基于脉宽调制的闭环控制方案,使扫描磁铁电源输出的电流为峰-峰值为0～8A可调,扫描频率为5～8Hz可调的连续三角波。该方案输出电流线性度好,闭环系统的快速性,鲁棒性均优于传统方案。
In this paper, a program to improve the scan magnet power supply was introduced. This program was based on the traditional non-linear approximation system and adopted a closed-loop PWM-based control program, which could control the output current of scan magnet power supply with peak-peak at 0-8 A, and scanning frequency with continuous triangular wave at 5-8 Hz. The output electric current linearity is better than traditional system. As a fast closed-loop system, the robustness is also superior to the traditional programs.
