Abstract: Power is the basic necessity for the economic development of country. Power consumption is increasing day by day at a very high rate. The modern system is so much dependent upon the use of electrical energy that it has become the part and parcel of our life. So we need to find out the causes of power loss and improve the power system. Due to industrialization the use of inductive load increases and hence power system losses its efficiency. So we need to improve the power factor with a suitable method. Now a days, the embedded is very much popular and most of the product are developed with microcontroller based embedded technology.

Keywords: Automatic power factor correction, microcontroller, embedded technology, capacitor bank.
