电源切换对系统工作影响分析与解决方案

摘要

In order to improve the system reliabihty, especially the system of power supply reliabihty, often need to provide two stable reliability in working power supply, a power failure can be rapidly switched to producing power, but switching circuit design and system for proper matching design, or in the power supply main standby path switching relay in switching, may cause the system to work abnormally, the fault reasons were analyzed, the switching circuit the paper puts forward an optimal scheme, and verified the correctness and feasibility of the optimization scheme.%为提高系统工作可靠性，尤其是系统供电的可靠性，经常需要提供两路稳定可靠性的工作电源，在一路电源出现故障时可以迅速切换到备路电源。但是切换电路的设计需要和系统进行适当的匹配设计，否则在电源主备路切换继电器在进行切换时。有可能导致系统工作异常，本文对故障产生原因进行了分析，对切换电路提出了优化改进方案，并通过试验验证了优化方案的正确性和可行性。
