an inverter converts Direct Current (DC) to Alternating Current (AC) or vice versa. A UPS consists of a battery charger, batteries (thus saving DC power), and an inverter (to convert to AC) all in one unit.
When the power goes off the supply of electricity to the battery charger part of the UPS is no longer fed, but the batteries still supply the inverter part (and ultimately whatever is running off of the UPS) with power until they run out.
The inverter alone is useless with out DC power supply (battery).

An Invertor and a UPS both convert DC Power from a Battery or Batteries into Main AC Power ( 120 / 240 Volts )
The UPS is powered directly from the mains power point and is contstantly ON all the time .
If the UPS senses a loss of the Main Power it immediately switches to the DC ( Battery ) Supply to give your equipment the mains power equivalent .
Applications included Computers , Telephone systems and any equipment that cannot be allowed to shut off in the event of a mains power failure .
A UPS is often called a No Break Power Supply since it does not interrupt the 120 / 240 Volts supply to the equipment it is connected to and hence that equipment does not shut off during the mains power disruption .
An invertor is usually used to supply mains power ( 120 / 240 Volts ) from a Car Battery to power equipment that needs Mains voltage , A common use is for camping or caravan applications where there is not access to mains power .

Inverter change supply from DC to AC but UPS is the source of uninterrupted power supply.UPS has inverter also. Inverter is the working unit of UPS,The mail parts of UPS are :- Rectifier,Battery bank,Inverter and Static switch.

An inverter converts Direct Current into Alternating current. (this is sometimes known as a "Chopper").
An Uninterruptable Power Supply consists of a rectifier (which converts alternating current into direct current), a battery, and an inverter. This means that should there be an outage (interruption of supply) to the input Alternating current, the battery will take over the output of the UPS so that there is no loss of power to any equipment which is connected to the UPS.

Simple.
Relay time is the duration within which the supply is restored back from mains to backup when power goes off and vice versa when the power comes back.
The relay time for Inverter is about 1/10 sec. That means that there is no supply to your appliances (PC, Fan, Bulb etc.) for about 1/10 sec whenever the power goes off or comes back.
The relay time for a UPS is about 1/40 sec ~ 1/100 sec. This means that for this much duration only, the supply to your appliances (mainly PCs, printers etc) will be interrupted.
For a computer circuit to retain its semiconductor logical states, the supply should not be interrupted for a duration more than that. Thats why inverter fails to keep your PC running when light goes off.

UPS is the only supplay the D.C.power to the electrical component like (computer,T.V.,Fan,etc.) continiusly and if the supply is more than 230 WT.then it will cut them and if the suppply is lower than 140 then supply more to that appropiate machin else it will stop supplying power to the machin.so that the machin never crash or fired.
Inverter is nothing but the backup system when ever light is gone the inverter will supply the power to the machin.

Inverter converts DC voltage to AC voltage. Useful in vehicles.
UPS, uninterpretable power supply, Standby power during power cuts, it is a battery and inverter in one unit, it enables you to close down computers safely and not lose work.

Inverter switches from AC to AC current without storing power
UPS switches from AC to DC when it detects a power cut, it restored power supply that it stored earlier when power was ON

inverter is when power converted from DC to AC. and ups all it is,
is just a power backup. its like a chargeable battery.

they both does the same work....but normally inverters are used in houses., stores....where more backup is required.....but UPS are used mainly for computer....inorder not to loose our work wen there is power loss....
