Department of Electrical/Electronic Engineering
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 â€�“UPSâ€Â� 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.
