UPS means uninterrupted power supply . It is used for
electronic instruments where continuous supply is
required . In UPS one battery bank is there which is used
for storage of power . When external supply is on the bank
get charged automatically . If supply goes off , this
stored DC voltage converted into AC voltage by a inbuilt
inverter . This o/p is fed to load . So a UPS consists of a
battery bank , a inverter circuit and associated
circuitry . There are various types of inverter like on
line , off line , line interuptive etc .

Answer / nilkanth

UPS means uninterupted supply for computer and electronic
devices.In the UPs one filter is use which mentained the
supply constantaly.There is Two types of UPs On line ups
and OFF line UPs.

Answer / vijayamohan

Hi Dears
UPS is for the purpose to give un-interruptible power
supply. This stores the energy in the form of DC by the
controlled rectifier (AC - DC converter) and discharge the
energy in the form of controlled AC by inverter (DC - AC
converter) so as to provide continuous power supply. Here
the back up is derived based on the requirement.

types:
1. Online Double convertion UPS (Normal High capacity UPS)
2. Online Delta convertion UPS (New technology offline
using buck boost Transformers)
3. Offline UPS (economical UPS medium capacity UPS 3 -
30KVA also available in higher capacity)
4. Line Interactive UPS (lower capacity UPS 300VA - max5KVA
output will be Squasi Sinewave).

UPS are used in home, medical, IT and industrial where the
critical load is used.

mail me for more information reqd.
Bye

Answer / engr. karuppiah mariappan

The UPS is uninterrupted power supply equipment. It contains the following
1. Rectifier - It will conver the AC power to DC
2. Battery Bank – It will store the charge and deliver the power to the inverter
3. DC - DC Converter – It will increase the DC voltage ( Like DC Booster)
4. Inverter - It will convert the DC Power to AC power and feed to the load
5. Static by pass switch – Incase any problem in the above it will divert the power from mains power supply to load
6. Manual by pass switch – It will use to take any maintenance or replacement of any modules / PCBs
5. Transient voltage and surge supression filter circuit – It will filter the unwanted surge / Harmonics.

Answer / tgfsd

ups means uninterupted power supply used to get continuous supply of current in the time of load shedding.it has three functions

POWER SUPPLY IS NOT AVAILABLE. AND IT MAINTAINS TO LOAD IN
ALL CONDITIONS.

Answer / neel patel

I can use many electronic devices, they are connected in series , power supply constant with connection and without connection both connection power will constant following. Thats known as the uninterrupted power supply (UPS).

Answer / nikunj

UPS means UNINTERRUPTIBLE POWER SUPPLY for any electronic devices. In the UPS one of the filter is use which mentained the supply continuously constant.

Answer / raman

Dear all,
I just want to know only one thing that which principle on
work our UPS.
For exam- Transformer work on a mutual induction principle.
So pls give me a actual ans.

u all are define use or details of parts,function of ups.

pls dont mind.
