An uninterruptible power supply is an electrical device that can provide short time power when the mains supply fails, ensuring the stable and uninterrupted power supply to electric equipment. In general, UPS can be divided into backup uninterruptible power supply, online uninterruptible power source, and line interactive UPS.

What is a UPS?

UPS is the acronym of uninterruptible power supply. Since computers and other sensitive equipment and gadgets require consistent supply of power of correct specification to ensure proper operation, they need a UPS. There are a number of types of UPSs on the market, including off line UPS, on line UPS and line interactive UPS, to name a few.

1. Off line UPS
Basically, offline UPS is similar to domestic inverter described above. There are two different types of off line UPS on the market, as described below.
(1) In comparison with an inverter, the offline UPS has a lower changeover time between the mains and battery. Typically, changeover time in inverters is 500 milliseconds, while that in an offline UPS is 3-8 milliseconds.
(2) When the mains is available, an inverter provides the output as is the input mains. However, offline UPS has a built-in automatic voltage regular or AVR to regulate the output voltage close to 220V AC. So, now, input voltage ranging from 150v to 270v can be regulated or stabilized by UPS, and when the voltage is not in this range, the system will shift to battery, so that the output remains uninterrupted.
Offline UPSs are normal weight UPSs and are widely used for domestic computers.

2. Line Interactive UPS
In line interactive UPS, the battery to AC power converter is always connected to the output of the UPS. Battery charging is done when the input AC power is normal, and when the input AC fails, the transfer switch opens and then the inverter starts functioning to provide power to load immediately.

3. On Line UPS
In online UPS, the system always remains on battery, whether mains AC is present or not. When mains AC is available, the on line UPS provides power to DC supply of inverter section, and simultaneously it charges the battery. When mains AC is unavailable, the online UPS will run the connected load till the battery has a recommended dischargeable level.
