| dc.description.abstract | AC loads are supplied by main source continuously. Sometimes, main source fails
caused of short circuit, fault, equipment problems from main source supply but the load
have to run. For this case another source is needed. Nowadays an uninterruptible power
system (UPS) has been widely used to protect various sensitive electrical equipments such as computers, workstations, telecommunications systems, internet data centers, and process
control systems. The UPS protects them from problems associated with utility power of
poor quality, or a complete loss of power. Furthermore, a UPS can also perform other
functions such as improving the quality of the power to the critical load.
In the Uninterruptible Power Supply (UPS) system, the failure of main source can
be solved by UPS Inverter. Normally, in the UPS system, the battery is charge using battery
charger from main source, but in this research the battery will be charge using solar charger
from Photovoltaic (PV). In this research, switch controller will be done by microcontroller
PIC16F628A. Project shows the successful results in design solar charger and design
switching controller of UPS using microcontroller PIC16F628A, meant it’s achieved
project objective. Testing shows system functions properly as needed. The reading of AC
load voltages and currents ares shows the good result. This experiment was tested at
Research Cluster UniMAP, Kangar, Perlis. | en_US |
