The uninterrupted power supply classification
Generally speaking, uninterrupted power supply can be divided into three categories according to its different working methods: backup, online and on-line interactive. The backup uninterrupted power supply operation is simple: when the power is normal, electricity will be provided directly to the computer equipment; when the utility power is disconnected, battery uninterrupted power supply inverter to the computer and other equipment power supply. That is to say that in most of the time is by city electric equipment for power supply, so the backup uninterrupted power supply for city power network exists on the surge, peak, frequency offset can be eliminated. But the uninterrupted power supply backup power capacity is small, but it has the advantages of simple technology, low cost, cheap price, and it will be suitable in voltage stability occasions. Line interactive uninterrupted power supply is also a backup job in uninterrupted power supply state, its working principle and common backup uninterrupted power supply are the same, because it is used in the three port type, increasing pressure stabilizing device, so that when the electric voltage and frequency are consistent with the target time, directly to the municipal power stabilizing pressure on equipment supply. On line interactive uninterrupted power supply is made in the perfect uninterrupted power supply structure, and the biggest difference lies in the online uninterrupted power supply inverter is that it always working, and it will be the first rectifier AC into DC power supply, inverter, at the same time to charge the battery, inverter in the DC inverse into AC output to the load; when city electrical voltage or frequency does not meet the requirements of the times, the inverter is powered by the battery to continue to support the work load; and when overload or inverter fault time, directly by the bypass to supply power to load. The biggest advantage of this way of working is that it will be the input and output completely isolate, avoiding electric in various fault and unstable factors, to conduct a comprehensive and thorough protection equipment.
Online uninterrupted power supply systems
Online uninterrupted power supply systems is a kind of tools can sale and buy automatic driving of power that can be effective to prevent driving circuit without the normal voltage. The online uninterrupted power supply systems are convenient for us. The uninterrupted power supply can be extended to the voltage circuit to make sure that the circuit can work normally. Mobile uninterrupted power supply and it is also called a battery backup, mobile power supply. Uninterrupted power supply itself is a battery pack that can be used for charging the mobile phone mobile power supply through the battery pack charging the electrical energy stored in the inside when the mobile phone has no power.
Uninterruptible power supply
An uninterruptible power supply, also uninterruptible power source, UPS or battery/flywheel backup, is an electrical apparatus that provides emergency power to a load when the input power source, typically mains power, fails. A UPS differs from an auxiliary or emergency power system or standby generator in that it will provide near-instantaneous protection from input power interruptions, by supplying energy stored in batteries or a flywheel.
