UPS stands for uninterrupt power supply..UPS r
INVERTER means the device which convers DC voltage into
AC.
As Electrical Engineering deals with High Voltage and
Electronic Engineering deals with Low Voltage....

Answer / mac

Dear kunal,
i dont know how much time you spended over this answer.

1. UPS is uninterrupted power supply with automatic
harmonic suppression characteristics such as rectification,
filteration of ripple content which makes it
uninterruptible for loads like computers or any other
electronic equipment

While,
Inverter is as simple as using a battery in case of
emergency, only the thing is that the addition of inverter
is for AC load. (to make it user friendly)
Inverter is best for Lighting load & worst for computers.

An UPS (uninterruptible power supply) is a device that supply power to your computer to running continuing when primary source or power is lost. It also protects our electronics gadgets during unnecessary power lost. UPS a power supply that includes a battery to maintain power in the event of a power outage. UPS are two basic types, One is: standby power systems (SPSs) and other is on-line UPS systems.



Inverter converts DC power (stored in its battery) to fulfill respective requirements of the devices.UPS does the similar task of power supply and is quite similar to inverters working in order to supply power.
Inverter has a wider range of input power as compared to UPS.

Answer / kunal

uninterrupt power supply is mainly use for short time .
means according to ups VA it gives backup.
ups is also two types : on line and offline . online ups
having high volt and amp for long time backup with with
high dc voltage.but ups start with 12v dc with 7 amp.
but inverter is startwith 12v,24,dc to 36v dc and 120amp to
180amp battery with long time backup.

Answer / mukund

all
please
think
over
on
this
again.............



Inverter

when the supply goes.....
the batteries discharge through inverter
to give back up

but the switching time is such slow
that we can fill the interuption of supply



ups

the switching time is such a faster using
thyristors so that it can be made in microsecond
does not make us fill the changeover
also not hampering the computers.

Answer / kunal

) CHANGE OVER TIME: An off-line ups (the standard) switches
to the batteries in 3 to 8 milliseconds, after the main
power has been lost.
The typical Inverter changes over in about 500 milliseconds

2) SIZE: Off-line UPS's go up to about 2kVA
Inverters go to 16kVA, 3 phase(what i could find browsing)

3)VOLTAGE REGULATION: UPS's have automatic voltage
regulation (AVR) set on average at 220v
Inverters output voltage is the same as the mains input
voltage (South Africa = 230V)



An inverter can transform a voltage from say 12volts dc and
up to 230v AC.

UPS means Uninteruptable Power Supply. If you use an UPS
between your computer, and your socket in the wall, and
experience a power failure, the UPS will act as a battery
and give you some extra minutes work time to save your
work, and turn of the machine properly. Without the UPS
your machine would die immediately


Electrical engineering, sometimes referred to as electrical
and electronic engineering, is a field of engineering that
deals with the study and application of electricity,
electronics and electromagnetism. The field first became an
identifiable occupation in the late nineteenth century
after commercialization of the electric telegraph and
electrical power supply. It now covers a range of subtopics
including power, electronics, control systems, signal
processing and telecommunications.

Electrical engineering may or may not include electronic
engineering. Where a distinction is made, usually outside
of the United States, electrical engineering is considered
to deal with the problems associated with large-scale
electrical systems such as power transmission and motor
control, whereas electronic engineering deals with the
study of small-scale electronic systems including computers
and integrated circuits.Alternatively, electrical engineers
are usually concerned with using electricity to transmit
energy, while electronic engineers are concerned with using
electricity to transmit information.

Answer / n. v. harikumar

UPS is the equipment for providing an uninterrupted power
supply to the load but inverter is for converting the DC
supply to AC supply at a constant voltage irrespective of
input voltage.Generally UPS is connectine in parallei to
the load or the load may be through UPS to avoid cutting
off the supply when an interruption in the source of
power.Generally UPS is a system having a battery and an
inverter. Battery will feed DC power to the inverter and it
convert the DC into a constant AC out put.

Answer / ankit

ups is used in industries for continuous ac
supply with battery bank. changeover
time is very fast...gives half to 1 hour
backup time to safely shut down of the
equipments.
And inverter is having comparatively more
changeover time..

Answer / pradeep

DEAR ITS SIMPLY MEANS UPS IS THE PART OF INVERTER...
UPS IS USE FOR SHORT TERM AND INVERTER FOR LONG TERM AS
ELECTRIC SUPPLY CONVERT DC TO AC..SO IT IS USED BY US AS
ELECTRICITY.. and pls write anything..

Answer / m.stalin

simply
ups - is uninterpted powersupply and this output wave form
is fully sign wave
2nd one inverter is off line power supply it will take
some Milli seconds to switching over- it was square wave output
