UNINTERRUPTIBLE POWER SUPPLY

TYPES OF UPS

Off-line Ups:

Offline UPS is also called as Standby UPS system as the inverter is in standby mode until the mains power supply fails.They are not expensive and recommended for home offices. Here, the primary source is the filtered AC mains (shown in solid path in figure 1). When the power breakage occurs, the transfer switch will select the backup source (shown in dashed path in figure 1). Thus we can clearly see that the stand by system will start working only when there is any failure in mains. In this system, the AC voltage is first rectified and stored in the storage battery connected to the rectifier.

When power breakage occurs, this DC voltage is converted to AC voltage by means of inverter and given to the load connected to it. This is the least expensive UPS system and it provides surge protection in addition to back up. The transfer time can be about 25 milliseconds which can be related to the time taken by the UPS system to detect the utility voltage that is lost. The block diagram is shown below.


An offline UPS provides battery power to equipment when the mains power supply falls below a pre-determined limit. Battery will usually last ten minutes.


Offline UPS units are often referred to as standby systems, as the inverter is in standby mode until the mains power supply fails. They are inexpensive and recommended for home offices. Offline technology should be avoided for applications where there is frequent power disturbance.



Line-Interactive Ups:

The line-interactive UPS is similar to a off-line UPS, but with the addition of a multi-tap variable-voltage autotransformer. This is a special type of transformer that can add or subtract powered coils of wire, thereby increasing or decreasing the magnetic field and the output voltage of the transformer. Additional filtering is provided in this UPS result in lower transient loss. Lline interactive UPS is used for small business and departmental servers and webs.

The block diagram is shown below.


Line-Interactive UPS is able to tolerate continuous under voltage brownouts and overvoltage surges without consuming the limited reserve battery power. It instead compensates by automatically selecting different power taps on the autotransformer. This has become popular even in the cheapest UPSs because it takes advantage of components already included. To gain the buck/boost feature, all that is required is two separate switches so that the AC input can be connected to one of the two primary taps, while the load is connected to the other, thus using the main transformer’s primary windings as an autotransformer. The battery can still be charged while “bucking” an overvoltage, but while “boosting” an under voltage, the transformer output is too low to charge the batteries.


On-line Ups:

The online UPS is ideal for the applications where electrical isolation is necessary and for the electronic equipments which are sensitive to power fluctuations. The initial cost of the online UPS may be slightly higher, but its total cost of ownership is generally lower due to longer battery life. The online UPS may be necessary when the power environment is “noisy”, when utility power sags, outages and other anomalies are frequent. This is extremely important when protection of sensitive IT equipment loads is required, or when operation from an extended-run backup generator is necessary.

The basic technology of the online UPS is the same as in a standby or line-interactive UPS. However it typically costs much more, due to it having a much greater current AC-to-DC battery-charger/rectifier, and with the rectifier and inverter designed to run continuously with improved cooling systems. It is called a double-conversion UPS due to the rectifier directly driving the inverter, even when powered from normal AC current.


In this type of UPS, double conversion method is used. Here, first the AC input is converted into DC by rectifying process for storing it in the rechargeable battery. This DC is converted into AC by the process of inversion and given to the load or equipment which it is connected (figure 2). This type of UPS is used where electrical isolation is mandatory. This system is a bit more costly due to the design of constantly running converters and cooling systems. Here, the rectifier which is powered with the normal AC current is directly driving the inverter. Hence it is also known as Double conversion UPS. The block diagram is shown above..


In an online UPS, the batteries are always connected to the inverter, so that no power transfer switches are necessary.



When power is restored, normal operation resumes and the rectifier continues to carry the electrical load and begins charging the batteries. The main advantage to the on-line UPS is its ability to provide an ‘electrical firewall’ between the incoming utility power and sensitive electronic equipment..

Look no where else further when comes to finding a quality UPS. ENSMART POWER carries many series of such UPS (Single phased or Three phased) that are catered to different customer’s needs..
