摘要: 本文提出了一个用于磁共振的高稳定度电磁铁稳流系统。消耗功率6kw时磁场强度为2.35T。介绍了系统的主要电路及调整测量方法。该系统的稳定度达到5×10-7/5分钟,长时间漂移为6×10-6/小时。该稳流系统原则上可适用于各种电源功率的电磁铁。

Abstract: This paper describes a highly stabilized magnet power supply system for magnetic resonance, which is capable of providing a field strenth of 2.35T in 6KW consumption. The main practical circuits and adjusted methods for stabilized system are given. The DC drift is about 5 part in 107 per 5 minutes and 6 part in 106 long-term(1h).
