Answer / ajayiet

both are ac to dc to ac
converters only difference is
switching speed based on use
of switches like mosfet gto
etc.ups operates faster than
inverter.

Answer / christopher vershima

Both ups and inverter work together to achieve a certain purpose but the difference is, inverters converts dc to ac while ups retains dc power when its battery must have been charged by the ac power converted to dc by rectifier

Answer / sundaresan.m

UPS - (Un interupted power supply) It is used when power
shut down it will gives the power as same as 23o volts upto
the EB power comes .

INVERTER- It is device which converts the AC supply to DC
supply and stores in the battery when EB supply is on and
when EB power shut down it will convert again the DC power
to AC power from the battery to switch boards through the UPS.

Answer / samy

1)inverter is when EB power is there what is input votlage
same out put voltage (eg: input 210v = output also 210v)
when EB power failure it will goes inverter mode (battery
mode )and voltage also increase as per inverter voltage
setting.

2)UPS is What ever input Eb voltage(eg:210v)output voltage
is as per the voltage setting (eg:230v) same when Eb power
failer same (battery mode) voltage is same eg:(230v) any
cost of time out put voltages is same .
