ABSTRACT
The
uninterruptible power supply (UPS) is design to help in the offices, workshops
and house hold appliances, due to the unstable power supply being supplied by
(NEPA) presently known as Power Holding Company of Nigeria (PHCN) usually
supply to us.
With the
help of the “UPS†we don’t need to depend much on PHCN it is stress free
because it don’t need someone to change it over when light goes off, once there
is any power failure it will automatically switched on and when power comes it
will switch off and start charging the battery.
Another
interesting thing in the UPS is that it does not need any external charger for
charging the battery when it goes low, it have already built charger inside the
UPS when there is light it will be charging the battery.
