UPS Full Form | Uninterruptible Power Supply – 2 Famous Type

UPS FULL FORM: Uninterruptible Power Supply

UPS full form is Uninterruptible Power Supply. It’s run with a battery to supply electricity to the sensitive equipment when there are primary sources is a failure. If the power supply is cut-off, then you can be supply power with the help of this UPS device. You can easily keep your work continuously for a short time when your electric device power is cut off. It is used for backup of current for an emergency. When power is cut off it switches to battery in few milliseconds. The Inverter circuit converts and provides only the battery’s DC current to the AC.

There are many UPSs are available on the market currently that provides technology that instantly saves your information and shuts down your pc. Battery size plays an essential role in UPS system selection. The environment has been affected adversely. To find the capacity of the UPS you have to find the load. The combined amount of power each of the devices used the load.

How does an Uninterruptible Power Supply works?

Many of you would be using your computer every day, which is connected to an uninterruptible power supply, also known as UPS rather than a wall socket. But how have you ever wondered how does a UPS work? Here we will understand their components, their working, the circuit of the motherboard and some variations of UPS design.

The UPS (UPS full form) consists of a battery, transformer, motherboard and a daughterboard for the front panel. The detailed information is always written on the UPS about the Model number, voltage regulation, application, initial current and some warning information.

The initial current that is mention on the UPS is less than or equal to the maximum charge, that should be supplied to the battery and when the battery reaches a certain level, then it charges slowly.

The battery is connected to the motherboard between the MOSFETs. The MOSFETs drains are connected to the secondary winding of the transformer.

The primary winding has four wires with different colours, black wire is common and other wires are different taps. These four wires are connected to the motherboard through the pin. There are two other wires(brown and black) that are connected to the output sockets and input is connected to the motherboard.

Motherboard parts consist of MOV or varistor, safety capacitor, filter capacitor, coupled inductor, fuse, charger circuit, four relays, full-bridge rectifier, battery monitor IC, charger control IC, snubber capacitor, diode, buzzer, and resistor. (some parts are shown below picture). When UPS is turned off, the ups can still charge the battery.

In the motherboard, the main part is Inverter, which converts DC from the battery to AC for the output. There are two or more MOSFETs in parallel to distribute the current. This high current also generates high heat, hence we you heatsink to dissipate it. The signal to these MOSFETs is provided by the controller. They are used to provide the high voltage to the gate of H-bridge MOSFETs from the low voltage signal of the controller.

There are some monitors to monitor the temperature which is coming from the MOSFETs. The transformer is used to change the voltage to the desired output (the desire output voltage is 340v).

What is prime role of UPS?

  1. Corrected the voltage spike (sustained overvoltage).
  2. Removing noise.
  3. Quick reduction in input voltage.
  4. Harmonic distortion.

Types of Uninterruptible Power Supply. :

Mainly there are two types or models of UPS full form systems. Which are given below.

  1. Offline ups full form
  2.  Online ups full form

Offline ups: It is also called a standby Power system.  you can make use of these types of offline ups when there is a sudden power cut-off. The connected devices switch to the ups battery power to give you a short time. This type of power system is widely used in computers and offline stores.

Offline UPS Circuit Connection:

Both offline and online have the same circuit connection but the main difference is UPS static switches are ON and OFF. The first static switch is On and the second is OFF.

The power supply is given to the rectifier circuit, this rectifier circuit converts the AC to DC. This DC current supply to the battery (for charging the battery) and as well as an inverter. The supplied DC current will convert DC to AC by the inventor. This inventor is connected with a UPS static switch.

This Offline UPS can be performed in two modes that are given below:
  1. Mode 1 (The main switch is ON)
  2. Mode 2 (The main switch is OFF)

Online ups: when the power is cut off for a long time, you can use this type of power system. It is a source of power continuously without any problems. normally almost this type of power system is used in function halls. There are two drawbacks, number one is, it’s costly and number second is it’s too loud because of the cooling fan. It provides power from its inverter without interruption. It is expensive compared to Offline USP. The input voltage range is 8 – 20kv online ups and output connections are hardwired.

Online UPS Circuit Connection:

In online UPS the circuit connection is almost the same as Offline UPS. Online UPS have a 1 or 3 phase power supply.

The power supply is given to the rectifier circuit, this rectifier circuit converts the AC to DC. This DC current supply to the battery (for charging the battery) and as well as an inverter. The supplied DC current will convert DC to AC by the inventor. This inventor is connected with a UPS static switch.

In this Online UPS, they are two UPS static switches. The basic condition of Online UPS is, the second UPS static switch is normally On and the first UPS static switch is normally OFF.

This Online UPS can be performed in three modes that are given below:
  1. Mode 1 (The main power supply is ON)
  2. Mode 2 (The main power supply is OFF and battery provide backup, the rectifier circuit not work in mode2)
  3. Power fails (The first UPS static switch will be ON automatically and second will be off automatically).

General Specification:

  • Power Rating: 1, 2, 5KVA
  • Out Put voltage: 250V +- 0.5%
  • Out Put frequency: 50 HZ +- 2HZ
  • In Put voltage: 190 V to 260V
  • Power factor: > 0.5 lagging
  • Back up time: 30min to hr

Other Design of Uninterruptible Power Supply:

There are four types of designs are available in the market that are listed below.

  1. Hybrid topology/double conversion on demand
  2. Ferroresonant
  3. DC power
  4. Rotary

Different types of Uninterruptible Power Supply Batteries.

Main there are three types of UPS batteries. Valve Regulated Lead Acid (VRLA), Flooded Cell or VLA batteries, Lithium-Ion batteries. The run time of the batteries of the ups totally depends on the size, type of the battery, some time rate of discharge and inverter efficiency.

Companies supply run-time ratings in minutes for packaged UPS systems. Larger systems (such as for data centres) need the detailed calculation of the load, inverter efficiency, and battery components to make sure the specified endurance is attained.

  • Common battery characteristics and load testing.
  • Testing of strings of batteries/cells.
  • Series-parallel battery interactions.
  • Series new/old battery interactions.

Advantages Uninterruptible Power Supply.

Why UPS needed?

There are many such electrical and equipment which if pack up suddenly can cause plenty of damage.

That is why an influence supply is required which may provide a couple of minutes of power backup just in case of power loss.

You imagine a situation where you’ve got prepared a project with 5 hours of diligence on your pc, and your computer shuts down thanks to a sudden power cut.

And your 5 hours of diligence goes vainly, if you had a UPS, then you’d have enough time just in case of an influence cut in order that you’ll save your work comfortably or continue your work by turning on the alternate power supply.

Many times there’s a disturbance somewhere within the supply route, suddenly the voltage goes down an excessive amount for a couple of milliseconds.
Due to which your computer or TV or other sensitive devices could also be packed up.

So UPS is additionally helpful during this condition and doesn’t allow your equipment to be packed up.

Many people believe that UPS is employed only with personal computers, which keeps our computer running even in the event of an influence cut for 10 to fifteen minutes.

While this is often not the case UPS is employed in personal computers to supercomputers, and even in big factories.
