双电源智能转换控制器设计

摘要

This paper takes CPLD EMP1270 as the core to accomplish the design of software and hardware of an intelligent double power supply controller .By using CPLD proprietary large-capacity cache chip ,it can greatly improve the performance of information transmission ,so as to shorten the simulation compilation time ,and increase the reliability of the intelligent dual-power switch and so on .System permits users to have different settings according to distribution network and load conditions ,to switch one power to another according to different breakdowns ,so the continuity of power supply is ensured .%以单片机CPLD EM P1270为核心进行双电源自动切换系统的软、硬件设计。利用CPLD专有的大容量高速缓存芯片，极大地改善了信息传输的性能，从而缩短了仿真编译时间，提高了双电源智能转换开关的可靠性、智能性、高效性等整体性能。根据不同故障情况实现对电源故障状况的准确判断并迅速切换，完成双电源间的转换，保证供电的连续性。
