Power factor is the ratio of active power consumed by the load in to the apparent power flowing in the system. So the power factor improvement is a major challenge in industrial, municipal, local and household application so as provide economical electricity to consumer demands as result reduce electricity bill. In this paper microcontroller based automatic power factor improvement is implemented in order to minimize electricity bill, reducing losses, and saving power. By observing power factor continuously, the power flow of the system can be improved sufficiently. In this paper PIC microcontroller static capacitors instead of high cost capacitor, to achieve the unity or near unity power factor parallel capacitor method is implemented in such way that number of small rating capacitors are connected to microcontroller so as to maintain the power factor close to unity by automatically connecting capacitors when according to requirement
