Abstract: Minimizing penalty is an issue related to industrial load is very much highlighted now a days. To overcome the above difficulties various methodologies has been designed and implemented. But few of them are sustain the issue of power consumption to certain extent with protective measurement. In this paper the technique used for design & implementation done with the help of microcontroller based APFC unit with motor load ,the result are verified before and after use of APFC unit. Power supply designs have been modified for necessity for improvement in performance of the system. Improving power factor means reducing the phase difference between voltage and current. Since majority of loads are of inductive nature in industry , they require some amount of reactive power for them to function. This reactive power is provided by the capacitor or bank of capacitors installed parallel to the load. Low power factor is expensive and inefficient. Many utility companies charge the users an additional fee if rate of power factor is less than 0.95. Low power factor also reduces your electrical system’s distribution capacity by increasing current flow and causing voltage drops. This fact sheet describes power factor and explains how you can improve your power factor to reduce electric bills and enhance your electrical system’s capacity
