FULLY AUTOMATIC POWER FACTOR COMPENSATION FOR INDUSTRIAL PURPOSE

The project is designed to minimize  penalty for industrial units  using automatic power factor correction unit. The micro controller used in this project belongs to 8051 family. In this proposed system, two zero crossing detectors are used for detecting  zero crossing of voltage and current.

The time lag between the zero-voltage pulse and zero-current pulse is duly generated by suitable operational amplifier circuits in comparator mode is fed to two interrupt pins of a micro controller. The program takes over to actuate appropriate number of relays from its output to bring shunt capacitors into load circuit to get the power factor till it reaches near unity. The capacitor bank and relays are interfaced to the micro controller using a relay driver. It displays time lag between the current and voltage on an LCD. Furthermore, the project can be enhanced by using relay control to avoid contact pitting often encountered by switching of capacitors due to high in rush current.

is the project for the last year engineering project, BE final year project. This project is use for the last year engineering student. It is the project for the microcontroller base project and zero crossing detector circuit for the detecting for the zero crossing circuit. This project is use for the comparator circuit.

this project is designed to minimize penalty for industrial units using APFC project for the BE final year engineering student

APFC for industrial use to minimize penalty is the project for the last year engineering student for the electrical department use for this project.

This project is use for the electronics engineering student is use for this project.it is use for the power electronics student for the BE final year student.

APFC is the project for the good project, excellent project for the BE last year engineering student. APFC is the project for the competitive project in the BE last year engineering student for electrical, electronics, power electronics student in last year engineering student.
