Power factor correction (PFC) is a technique of counteracting the undesirable effects of electric loads that create a power factor that is less than one. In this study, many small rating capacitors are connected in parallel and a reference power factor is set as standard value into the Microcontroller 16F877A IC. Suitable number of static capacitors is automatically connected according to the instruction of the Microcontroller 16F877A to improve the power factor close to unity. Many control methods for the Power Factor Correction (PFC) have been proposed. This work describes the design and development of a power factor corrector using PIC (Programmable Interface Controller) Microcontroller 16F877A chip. Measuring of power factor from load is achieved by using PIC Microcontroller 16F877A-based developed algorithm to determine and trigger sufficient switching of capacitors in order to compensate demand of excessive reactive power locally, thus bringing power factor near to unity.
