UPS means uninterrupted power supply . It is used for
electronic instruments where continuous supply is
required . In UPS one battery bank is there which is used
for storage of power . When external supply is on the bank
get charged automatically . If supply goes off , this
stored DC voltage converted into AC voltage by a inbuilt
inverter . This o/p is fed to load . So a UPS consists of a
battery bank , a inverter circuit and associated
circuitry . There are various types of inverter like on
line , off line , line interuptive etc .
