Answer Posted / pravesh
the difference between the inverter and ups is that in
inverter it converts dc voltage into ac voltage by using
battery while in ups as the name suggests that un-
interrupted power supply it works even when the supply is
there but there is interruption due to sinusoidal wave
which creats distortion in electronic equipments working
hence ups maintains the power supply level .
