Answer / doli tomar
The basic difference in layman's terms is:
While both provide backup power during mains outage, with
the UPS the switch is instantaneous whereas with the
Inverter there is a gap of a second or two. This gap is OK
for household gadgets such as lights, fans, fridge, etc.
but not OK for computers.
In technical terms:
UPS: The mains power comes to the UPS. The AC is converted
to DC and this DC is constantly charging the battery. The
output of the battery is fed to the Sine wave inverter and
it converts DC to AC and this feeds the equipment. Since
power out is always drawn from the battery, there is no
time lag when mains swicthes off; it justs stops the
battery from being charged and the UPS continues to supply
power till the battery runs out.
Inverter: The mains power comes to the Inverter. This is
directly sent to the output but the AC is also converted to
DC and this DC is constantly charging the battery. A sensor
and relay mechanism checks whether the mains is ON or OFF.
When the main switches OFF, the relay actuator triggers to
switch from mains to inverter. Rest is same like the UPS.
Because of this sensor and relay, there is a gap between
triggering.
UPS involves more costly circuitary and is therefor more
expensive to make and sell.

Answer / vinod bisht
UPS-IT STANDS FOR UNINTERRUPTED POWER SUPPLY
INVERTER-ACTUALLY INVERTS(CHANGES) DC SUPPLY INTO AC SUPPLY.
UPS CONSISTS BATTERY ,BATTERY CHARGER AND INVERTER.
