Hi this is Arun Reddy. UPS means Uniterrupted power supply.
The main parts are Converter,Inverter,Batteries,Rectifier.
Converter: It converts AC to DC Supply. The DC supply goes
to battery to charge.
Inverter: It converts DC to AC Supply.
Battery: It takes DC power means output of Converter & We
get DC power output from Batt. When the power comes to
Inverter it will become AC power.
Rectifier: It converts AC to DC Supply. It used Before the
Batteries in UPS System.

Thanking You.
