Minimizing Penalty in Industrial Engaging Using APFC Unit

Abstract

This project is mainly proposed for reducing the powers loss in industries by using power factor compensation through a number of shunt capacitors. Power factor is defined as the ratio of real power to apparent power. So, the increase in reactive power (real power) increases apparent power, so the power factor also decreases. By having low power factor, the industry needs more energy to meet its demand, so the efficiency decreases. In this system, we proposed the time lag between zero voltage pulse and zero current pulse delay generated by suitable op-amp circuits in comparator mode and fed into two interrupt pins in microcontroller. Microcontroller displays the power loss due to inductive load on the LCD.
