摘要: 针对现有的UPS切换判别方法会导致误动作的问题，采用DSP技术设计了一种UPS快速切换判别方法。该方法采用软件锁相方式，根据DSP采集并处理得到的交流电压幅值和相位进行掉电检测和电压跌落检测，当检测值超过设定范围时进行UPS切换。实验结果表明，该方法能够快速、准确地判断出交流掉电和电压跌落，在1 ms左右时间内实现UPS切换。

Abstract: For incorrect operation of existing identification methods for UPS switching, an identification method for UPS rapid switching was designed by use of DSP technology. The method uses software lock mode, and adopts AC voltage amplitude and phase signals colleted and processed by DSP to measure power fail and voltage drop. When the measured value exceeds the setting one, USP would be switched. The experimental result shows the method can determine AC power fail and voltage drop, and achieve UPS switching in about 1 ms.
