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 .

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

of line but on pressing start button nothing happens. is it
possible to switched on the same ups without connecting the
dc source.

The main building blocks of any given UPS (on-line, off-line
or stand-by) are the charger, inverter, static switch or
static disconnect and battery. The charger converts AC to DC
power which float charge is the battery and feeds
the inverter. The inverter converts DC to AC power, and the
static switch or static disconnect is a solid-state device
used to apply or disconnect AC power. The battery stores DC
power that is used as a back-up power source when
the utility power is not available.
