摘　　要：大型加速器电源系统可靠工作对整个加速器的长期有效运行具有重要意义,在当前可实施的电源技术下,采用N+1模块化自均衡并联冗余电源可明显提高电源系统的可靠性。本文对这种结构的磁铁稳流电源进行了研发及可靠性分析,并对电源的可靠性进行了估算。结果表明,该电源1a故障时间(MTTR)比单个模块少1/3;上半年的MTTR小于单个模块的1/2。N+1模块化自均衡并联冗余电源的故障率呈现前期低、后期高的特点,且这种电源在电源可靠度高时能展现更大的可靠性优势,是加速器电源的理想选择。The reliable operation of the power supply system is of great significance to the long-term efficient operation of the entire large accelerator.The N+1 modular self-balanced parallel redundant power supply can significantly improve the reliability of the power supply system under the currently executable power supply technology.The research and reliability analysis of the magnet power supply for this structure were carried out,and the reliability of the power supply was estimated in this paper.The result shows that the MTTR of the power supply is one-third less than that of a single module in one year,and the MTTR of the power supply is less than 1/2 of a single module MTTR in the first half of the year.The failure rate of N+1 modular self-balanced parallel redundant power supply shows the feature of low in early stage and high in late stage.This kind of power supply has greater advantage in reliability when the reliability of the power supply is high,and is an ideal choice for an accelerator power supply.
