ABSTRACT
This
uninterruptible power supplies device has the capability of converting from
12volts D.C to 220volts alternating current at the frequency of 50Hz with the
help of a step-up transformer. The main importance of this device is its
ability to ensure absolute continuity of power to the computerized control
system thereby protecting a critical equipment from electrical supply failure.
Ups system achieve this by rectifying the mains supply, using the direct
current to charge the standby battery and to produce a “clean†alternating
current by passing through an inverter and filter system. The output produced
is free of sags of services in the line voltage, frequency variation, spikes
and transients.
