超高稳定度电源研制

文章介绍了在离子加速器及核磁共振设备上使用的一种超高稳定度磁铁线性电源。采用的设计方案是用调压器或可控硅调压,保证功率三极管CE两端的管压降保持在合理的范围内,采用高精密采样、比较、控制环节保证电流的稳定度。文中简述了该电源的控制原理、技术性能及采用的一些保护措施。

A linear power supply for ultra-high stability magnets used in ion accelerators and nuclear magnetic resonance （NMR）equipment is introduced in this paper. The adopted design scheme is to use voltage regulator or SCR to adjust the voltage to ensurethat the voltage drop at both ends of the power Triode CE is kept within a reasonable range, and to adopt high precision sampling,comparison and control links to ensure the stability of the current. The control principle, technical performance and some protectivemeasures of the power supply are briefly described in this paper.
