The UPS is a device which provide us the continuous power
without any breaking in normal supply.Due to requirement of
continuous supply for critical load UPSes are get used in
IT companies as well as for Non IT companies.
Untruptted Power Supply (UPS )-have mainly five parts-
Rectifier,Battery Bank,Inverter,Switching & controlling
devices.Their working is based on logic controll.
At the presence of normal electric supply the load flows
from Rectifier-Inverter-Switch but when AC supply in not
presented at all then Battery units come into picture.By
the working principal or inverter i.e. from DC -AC it
feeded AC supply to the load after Ac filterisation.
When there are any problem in Rectifier ,inverter, Battery
etc. unit then supply goes through bypass.
Isolating transformer is a type of X-mer which isolate the
a circuit to its design.and also the No. of primary
&Secondary tern of Iso. X-mer are same are equal that
facilitates to isolates and reduce the fluctuation and also
create Neutral supply for load.
