摘　　要：不间断电源UPS的核心是电源质量的检测与切换,当市电出现异常时,需要快速地将负载切换到后备电源供电。为了保证检测切换的正常进行,该文设计了一种基于DSP的快速检测方案,通过将检测到的波形与预先设定的标准波形进行对比实现检测。该系统在保证抗干扰性、切换可靠性的同时,提高了数字化程度,精简了元器件数量,降低了成本以及体积,对类似的其它系统有一定的参考意义。The concentration of uninterruptible power Supply（UPS） is the electricity power down detection and the switch betweenthe powers,When theiclty electricity is cut off, the load should be switched to inverter order guarantee the swltch smoothly earned on, this new method of city e- to. supplypower by leemecity power-down detectiop based on DSP P is designed,which is focused on ：the ebmparison between thewaveform detected from the real city electricity and the standard waveform digitization. This digital control system is su erior in anti-j/tmming and tel!able in switch, which hasl improved the digital level, reduced the com- ponent count, the cost and the size. iThis method has a certain reference value to similar systems.
