Answer Posted / sudha
in on-line ups the inverter will be always ON.the power
flows from supply to load through battery and inverter.but
in off-line ups inverter will be ON only when supply is
cutoff.in this power flows directly to the load through a
seperate static switch..
The inverter in on-line should be high efficient and also
change over time is very less in online ups than offline..
