The voltage stability of the ac system has become a significant source of concern in recent decades because to the dramatic increase in electronic devices, power systems, and high-voltage electrical systems. The bulk of industrial and commercial systems across the country have large, multiple-inductive electrical loads, which causes a low power factor and heavy penalties from the electricity board for customers. PFC is in charge of this. Fixed loadsonly operated with manually by switching capacitors, but when dealing with distributed loads that fluctuate rapidly. In order to change the load by manually seems to be more struggle to reach the high level. To circumvent this issue, an APFC panel is utilised. The PIC microcontroller used in this study measures power factor from the load and activates the required capacitors.
