Difference between ups and invertor

Inverter:
The proper meaning of inverter is a device which
converts dc into ac.
The inverter also contains a battery unit and an dc to to ac
conversion unit. when the power fails the inveter will
deliver power from switching from main source to battery
source. The switching time here is normally greater than 20
ms.
UPS:
The proper meaning of this is a device, which delivers
power, even if the source power fails(Uninterrupted power
supply).
This is also contains the same thing as a inverter except
here the switching time from main source to backup source is
less than 10ms, so that the computer hard drives or an
sensitive power products should not be affected from this.
Depending on the switching time there is a online ups and
offline ups. off line ups is same as a inverter.

Answer / aravind bandaru
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.

Answer / praful nandankar
Both depends on switching time. The word UPS means
uninterrupted power supply. The power switches from main
source to UPS within milliseconds. Inverter switches after
20 milliseconds.
