UPS based on capacitor battery and construction method thereof

Abstract

The invention discloses a UPS (Uninterruptible Power Supply) based on a capacitor battery, which comprises an input filter, a rectifier, an inverter, a static switch, an output filter, a charger and acapacitor battery. The input filter, the rectifier, the inverter, the static switch and the output filter are connected in turn. The input end of the charger is connected with the output end of the input filter. The output end of the charger is connected with the capacitor battery. The output end of the capacitor battery is connected with the input end of the inverter. A construction method of the UPS includes the following steps: calculating the required capacitance according to the power of most existing computers; making a UPS according to the capacitance; connecting the UPS with a computer, and charging the UPS until the power is sufficient; and judging whether the desktop computer is powered off, and starting the UPS if it is determined that the desktop computer is powered off. The UPS based on a capacitor battery is a UPS which is safe and reliable and has high accuracy and strong real-time performance.

Description

Technical field: [0001] The invention relates to the technical field of UPS power supply, in particular to a capacitor battery-based UPS uninterruptible power supply and a construction method thereof. Background technique: [0002] With the rapid development of society's informatization and modernization process, and the gradual improvement of people's living standards, users have higher and higher requirements for power supply reliability. Important event places such as government agencies, gymnasiums, large hospitals, and large conference centers, etc., in the event of a power outage, the consequences are unimaginable, which will not only disrupt normal production and living arrangements, but also cause certain economic losses and serious negative social influence. Therefore, uninterruptible power supply technology needs to be studied to maintain a normal and stable social life order. [0003] At present, information is exploding at a high speed, how to prevent data loss...

AI Technical Summary

Problems solved by technology

The energy in the supercapacitor is stored on the electrode and the surface of the electrolyte in the form of static charge, and the charging and discharging process is almost a physical process. Therefore, overcharging and overdischarging have little impact on the life of the supercapacitor, and there is no memory effect

Compared with batteries, supercapacitors have extremely high cycle life (usually greater than 500,000 times) and power density, but their energy density is very low (10-30W h / L)

[0005] Aiming at the problem that important things such as computer files and projects are suddenly damaged in the case of sudden power failure or power disconnection of existing desktop computers, the current battery-based UPS power supply is expensive and is generally used in important security units, such as broadcasting radio station, factory, etc.

And battery-based UPS overcharge and overdischarge both lead to short battery life
