并联冗余UPS系统静态转换开关的设计与实现

Design and Implementation of Static Transfer Switch in Parallel UPS

文中主要介绍模块化并联冗余UPS系统静态转换开关的应用设计。转换开关采用并联组合式切换开关结构，在系统并联运行时，由DsP监控系统来统一集中控制主-旁路切换功能，实现快速切换和系统保护等一系列控制功能。功能样机的实验结果验证了该智能控制方案的有效性。

The application and design of Static Transfer Switch for Modular Parallel Redundant UPS is proposed in this paper. It adopts the structure of parallel-combined transfer switch. When the system is under parallel operation, the DSP centralized monitoring system control the mainbackup switching, fast transfer-switching, protection and other control functions. And the results from the experiment verify the validity of the scheme.
