Design of Industry-used Redundancy Power Supply Based on LTC4357
-
摘要: 在工业现场中常因供电设备的单点故障问题引起设备的损坏,从而对生产造成损失。针对该问题,文章提出了一种基于LTC4357的工业用冗余电源的解决方案,阐述了N+1冗余方式的原理,详细介绍了基于LTC4357的冗余电源中冗余模块的设计,指出了直流稳压电源模块在工业现场应用过程中出现的问题及解决方法,最后给出了冗余电源实物图。实际应用表明,该方案具有一定的可行性。Abstract: Single fault problem of power supply equipments often induces damage of equipments in industrial field,so as to cause loss for production.Aiming at the problem,the paper proposed a solution of industry-used redundancy power supply based on LTC4357.It expounded the principle of N+1 redundancy mode,introduced design of the redundancy module in the redundancy power supply in details,and indicated the problems and solutions when the DC regulated power supply module was used in industrial filed.At last,it gave real graph of the redundancy power supply.The actual application showed that the scheme has certain feasibility.
