This abstract presents a microcontroller-based Automatic Power Factor Correction (APFC) panel design that continuously monitors and optimizes power factor by dynamically switching capacitor banks to compensate for reactive power, thereby improving system efficiency and reducing energy costs.Power factor is a crucial aspect of electrical systems, reflecting the efficiency with which electrical power is converted into useful work output. A low power factor indicates poor efficiency and results in higher energy costs and increased strain on the electrical infrastructure. Automatic Power Factor Correction (APFC) systems help maintain the power factor close to unity by automatically compensating for reactive power. Microcontroller IC (AT89C51) reduce programming complexity that make it one of the most economical system than any other controlling system.Automatic Power factor correction is the capacity of absorbing the reactive power produced by a load. In case of fixed loads, this can be done manually by switching of capacitors, however in case of rapidly varying and scattered loads it becomes difficult to maintain a high power factor by manually switching on/off the capacitors in proportion to variation of load within an installation. This drawback is overcome by using an APFC panel. In recent years, the power quality of the ac system has become great concern due to the rapidly increased numbers of electronic equipment, power electronics and high voltage power system. most of the commercial and industrial installation in the country has large electrical loads which are severally inductive in nature causing lagging power factor which gives heavy penalties to consumer by electricity board. This situation is taken care by APFC .
