UPS 也称不间断电源,它是英文 Uninterruptible Power System 的缩写,是一种含有储能装置、以逆变器为主要组成部分的恒频恒压式交流不间断电源。计算机的电源,应十分可靠,但电网的质量往往不尽如人意:电压浪涌、电压瞬变、电压跌落、持续过高或低压、电压光峰甚至供电中断等等威胁,在各国各地区都不同程度地存在着。尽管波动或中断的时间非常短,但由于计算机的微处理器灵敏度很高,数据传递的速度极快,因而很可能造成丢失信息或者改变信息,硬盘程序被冲掉等严重后果,且电路中的
UPS, also known as uninterruptible power supply, is an acronym for English Uninterruptible Power System. It is a kind of constant frequency constant voltage AC uninterruptible power supply with energy storage device and inverter as main components. Computer power supply should be very reliable, but the quality of the power grid often unsatisfactory: voltage surge, voltage transients, voltage sags, sustained high or low voltage, voltage peak or even power supply interruption and so threatening in all regions of the country To varying degrees exist. Although the fluctuation or interruption time is very short, the high sensitivity of the microprocessor of the computer and the extremely fast data transfer speed may cause serious consequences such as loss of information or change of information and flushing of the hard disk program. In addition,
