电源中的容错技术

Fault Tolerance Technique In Power Supply

为了满足用户高可靠,不停电供电的需求,作者提出了可以将大型电子系统的供电电源视作一个实时控制系统的概念,在电源设计中采用容错技术。接着,对电源中的容错技术和冗余技术的基本概念作了简要的阐述。文章重点讨论了交流不停电电源UPS系统,一次直流电源系统和二次电源中的容错技术。

In order to satisfy user's requirements for high reliability and uninterruptible power supply,this paper proposes the concept of treating the power supply of large electrical system as a realtime controlling system, and the method of applying fault tolerance in power design. Then, the paper gives brief introduction on the basic concept of fault tolerance and redundance technique in power supply. The paper puts emphasis on fault tolerance technology in alternating current uninterruptible power supply (UPS) system,and primary order DC power supply system and second ordor DC power supply system.
